▎ 摘  要

NOVELTY - Conductive laminate comprises at least a conductive layer and a conductive hot-melt adhesive layer in contact with the conductive layer on a substrate, where the volume resistivity of the conductive hot-melt adhesive layer is 1x 10-1 to 1x 103 Omega cm, and the volume resistivity of the conductive layer is 1x 10-5 to 1x 100 Omega cm. USE - The conductive laminate is useful for forming adhesive structure, natural potential sensor and chloride ion sensor. ADVANTAGE - The conductive laminate firmly adheres to the adherend in a state of exhibiting high conductivity, and acquires electric signal inside adherend in a state of being easily and firmly adhered to material such as wood. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an adhesive structure comprising the above-mentioned conductive laminate and an adherend are laminated; (2) a natural potential sensor capable of measuring deterioration of reinforcing bars existing inside concrete through a signal obtained from the conductive laminate; (3) a chloride ion sensor capable of measuring the chloride ion concentration inside concrete through a signal obtained from the conductive laminate; and (4) a method for producing the conductive laminate, involving printing the conductive layer on the substrate, and printing the conductive hot melt adhesive layer.
