Printed circuit board for degradation detection

Abstract

Provided is a printed circuit board for degradation detection, the printed circuit board having an insulator substrate and a wiring pattern for degradation detection, the wiring pattern being formed on an outer surface of the insulator substrate, and the printed circuit board for degradation detection being attached to a main printed circuit board for which degradation is to be detected. The wiring pattern is formed on, of the outer surfaces of the insulator substrate, a back surface positioned on the main printed circuit board side. The insulator substrate has a penetrating part (through hole, notch part) penetrating from the back surface to a front surface positioned on the side opposite from the back surface.
