▎ 摘　　要

NOVELTY - A layer (6) of a support material is formed on the surface of a layer of graphene (1) formed on an initial stage substrate for graphene. A water passage hole is formed in the layer of the support material. The initial stage substrate for graphene is removed. A water passage hole is formed in the graphene layer by carrying out low temperature heating and retaining the graphene layer in air containing oxygen at 160-250 degrees C for predetermined time, to obtain a molded filter material which has a graphene layer as filter medium. USE - Manufacture of molded filter material (claimed). ADVANTAGE - The method enables efficient manufacture of molded filter material having water passage holes of required size, without damaging support material and graphene pollution. DESCRIPTION OF DRAWING(S) - The drawing shows the explanatory view of manufacture of molded filter material. Graphene (1) Copper foil (2) Film resist (3) Resist layer (5) Support layer (6)
