成される、近接スイッチ。In a proximity switch including a coil, a core, and an oscillating means that operates in oscillation in cooperation with the coil and oscillates at a frequency corresponding to an induced change in the coil, the core accommodates the coil on one surface in the axial direction. A storage recess is formed and said storage recess. A through hole for connecting a lead wire of a coil to the oscillating means is formed at the bottom of the proximity switch, and the axial length of the through hole is at least twice the depth of the storage recess.
