In an electric member having a number of leads such as in a remote-controlled light receiving module, loosening prevention kinks created on at least one of the leads are shaped such that the shorter the distance from the loosening prevention kink to the tip of the lead the thinner the loosening prevention kink. When the electric member is mounted on a printed circuit board, the leads are inserted into wiring through-holes on the printed circuit board by pressing the electric member against the board, allowing the position and orientation of the electric member to be firmly fixed automatically by virtue of the loosening prevention kinks.
