PROBLEM TO BE SOLVED: To suppress wear of a circuit board at a holding portion, in a circuit board which is fixed while being held by a mechanical structure.SOLUTION: A circuit board (102) fixed while being held between two supports (104b, 106b), i.e., a mechanical structure, has through holes, i.e., slits (230-236), along a part of the outer periphery of the holding regions (210, 212) by the supports. The slit is formed at a position where a part of the outer periphery comes into contact with a part of the outer periphery of the holding region, or a position within a range of a predetermined distance from the outer periphery of the holding region, thus reducing a stress generated in the holding region. |
