PROBLEM TO BE SOLVED: To enable to achieve simple design/production of products to various product specifications without several characteristic adjustments even if outer shell cases of different materials are combined. SOLUTION: A proximity sensor 717 comprises a combination of an arbitrarily selected one each of a plurality of types of detection end modules 707, a plurality of types of output circuit modules 709 and a plurality of types of outer shell cases 711. The detection end module 707 includes an integrated arrangement having detection coil assemblies (705, 701, 702) with the detection characteristics self-completed by a mask conductor 700 for reducing conductor detection sensitivity in a specific peripheral area where the outer shell case is assumed to exist, and a detection circuit assembly (703) with coils of the detection coil assemblies as a resonance circuit element. The characteristics of the proximity sensor are completely adjusted before shipment. COPYRIGHT: (C)2007,JPO&INPIT
