Abstract
To provide a printed circuit board that allows for easy exchange of only a deterioration detection conductor, and can reduce costs. A printed circuit board includes: a main printed circuit board in which a wiring pattern is formed on an insulated substrate; and a deterioration detection wiring board in which deterioration detection wiring (deterioration detection wiring pattern) which is wiring having a form whereby deterioration is promoted compared to the wiring pattern on the insulated substrate is formed on a separate insulated substrate from the main printed circuit board, and is exchangeably connected to the main printed circuit board in a vicinity thereof by way of a replacement-enabling connection part. One mode of the replacement-enabling connection part of the printed circuit board is a connection part (solder joint) constituted by solder, another mode thereof is a connection part (electrically conductive adhesive connection part) constituted by electrically conductive adhesive, and yet another mode thereof is a connection part (cable) constituted by a cable.
