    In one antenna unit (10), a non-electrically conductive resin layer (36a) is provided on a core portion (36) of electrically conductive material and a winding portion (37) is configured by a coil wound on the layer. The antenna unit is housed in a band attaching portion of a watch case of a watch, and a watch module is housed in the watch case. In another antenna unit, a core portion and a winding portion wound on the core portion are arranged in a cover case (31). Openings (45a) are formed in side walls of the cover case oppositely positioned to each other, and parts (37a) of the outer circumferential surface of the winding portion are arranged in the openings. The winding portion together with the core portion is supported to the inner surface of the cover case by adhesive portions (32) interposed between the cover case and the winding portion.
