NOVELTY - The method involves generating frictional heat at a portion where fine particles of the metal come into contact with fine particles of the metal oxide forming the insulating layer. The fine particles of the metal are bonded to fine particles of the metal oxide. Friction heat is generated at portions where fine particles of the metal are in contact with each other. The fine particles of the metal are bonded by the friction heat. A conductive layer is formed on an insulating layer of a graphene bonded structure. The conductive layer of a predetermined shape consisting of a collection of fine particles of the metal is formed on an insulating layer of the graphene bonded structure. Collection of graphene is manufactured from a collection of graphite particles. The graphenes (1) are superposed on each other to form a graphene bonded structure. The insulating layer and the conductive layer are formed on the surface of the graphene bonded structure. USE - Method for manufacturing graphene bonded structure by manufacturing collection of graphenes from collection of graphite particles. ADVANTAGE - The large amount of graphenes is manufactured at low cost by extremely simple process of applying electric field to collection of inexpensive graphite particles. DETAILED DESCRIPTION - The collection of scaly graphite particles or collection of massive graphite particles is drawn on surface of one of two parallel plate electrodes. A parallel plate electrode is immersed in methanol filled in a container. The other parallel plate electrode is superposed on the one parallel flat plate electrode. The separated 2 parallel plate electrodes are immersed in methanol. Direct current (DC) potential difference of a predetermined size is applied to the gap between the 2 parallel plate electrodes. The collection of graphene is produced from a collection of graphite particles in methanol. The graphene bonded structure is formed by superposing graphenes. The electrically conductive paste is manufactured by mixing organic compound having higher viscosity than methanol and boiling point lower than temperature at which metal compound for depositing the metal thermally decomposes is mixed with the methanol dispersion to produce a conductive paste. The insulating layer is formed on the surface of the graphene bonded structure. The conductive paste is coated or printed in a predetermined shape at a predetermined position on the insulating layer of the graphene bonded structure on which the insulating layer is formed. A coating film or a printed film comprising an electrically conductive paste is formed. The graphene bonded structure is placed in a heat treatment device in an air atmosphere. The heat treatment device is heated to a thermal decomposition temperature of a metal compound constituting the conductive paste. The collection of metal fine particles is deposited on an insulating layer of the graphene bonded structure. The metal compound has a first property of depositing a metal oxide by thermal decomposition in an air atmosphere and a second property of being dispersed in methanol is combined with aluminum caprylate, aluminum benzoate, and aluminum benzoate. The organic compound has a first property of being an aluminum carboxylate compound composed of aluminum naphthenate, dissolving or miscible in methanol, second property having a viscosity higher than methanol, and third property having boiling point lower than temperature at which the metal compound decomposes thermally, including any of esters of carboxylic acid vinyl esters, acrylic esters, and methacrylic esters.
