PURPOSE: To acquire conduction readily and surely by acquiring a curing matter whose essential elements are synthetic resin and conductive powder and conductive powder is separated and precipitated from a synthetic 9& resin layer during curing, thus forming a double layer structure of a synthetic resin layer and a conductive powder layer.

CONSTITUTION: As synthetic resin, thermosetting resin, thermoplastic resin or mixture resin thereof is used. As conductive powder, gold powder, silver powder, copper powder, nickel powder, carbon powder, powder with a conductive layer in a surface, etc., single or a mixture of two or more kinds thereof is used. Essential elements of a conductive resin composition is synthetic resin and conductive powder, and a small amount of solvent, coupling agent and other additive for viscosity adjustment are mixed. In the conductive resin composition, conductive powder is separated and precipitated during curing and a molded item of a double layer structure of a synthetic resin layer and a conductive powder layer is acquired. Conduction can be acquired surely without the necessity for increasing an amount of metallic insert and conductive filler by using the conductive powder layer.
