Abstract
An electric device includes a substrate on which electronic components are mounted, and a metal plate to which the substrate is fixed. The metal plate includes first bosses provided at positions corresponding to four corners of the substrate, a second boss provided inside a rectangle that connects the four first bosses, and a slit that is provided adjacent to the second boss, and extends in non-parallel with any side of the rectangle. The substrate is fixed to each of the four first bosses with a first male screw, such that a rubber washer is sandwiched between the substrate and the first male screw. The substrate is fixed to the second boss with a second male screw, such that no rubber washer is sandwiched between the substrate and the second male screw.
