摘要: A circuit board comprises wiring parts containing silver on a substrate, and a conductivity suppressing agent such as a potassium compound provided between the wiring parts, for preventing the silver attached on the substrate between the wiring parts from being conductive. Therefore, the insulation deterioration between the wiring parts can be suitably suppressed, which usually occurs when a voltage is applied between the wiring parts containing silver on the substrate under a high temperature atmosphere, irrespective of the presence or absence of water or water vapor. That is, the high temperature leakage phenomenon can be suitably suppressed.
