を目的とするものである。Problems to be Solved by the Invention In recent years, membrane switches have become mainstream for keyboard switches in response to market demands for lower prices. Now, for the contact part of a membrane switch, a spacer is sandwiched between two polyester films (upper and lower), on which the contact part and the circuit pattern connecting it are printed with conductive paint, to create an appropriate gap between the opposing contact parts. In response to the miniaturization and thinning of keyboards, the polyester film is sometimes used by folding it.However, with conventional conductive paints, if only scaly silver powder is used as the conductive material, The resistance of the folded circuit pattern increases. If only dendritic silver powder is used, the hardness of the coating film will be poor. Furthermore, when a hydrocarbon type solvent is used, the compatibility becomes 1.0%, and when an alcohol type solvent is used, there is a problem that the resistance value increases due to reaction with the resin. The object of the present invention is to provide a conductive paint that solves these conventional problems.
