To protect a cover member from impact of dropping or the like.

This electronic wristwatch is provided with a wristwatch case 1 provided in an outer circumferential part with a housing recessed part 12, an antenna 4 housed in the housing recessed part 12, a cover member 14 fixed to the housing recessed part 12 and covering the antenna 4, and a bezel 15 provided with a securing part 16 attached to the outer circumferential part in an upper face of the wristwatch case 1 and securing the cover member 14 by covering almost half of it. Accordingly, since almost half of the cover member 14 fixed to the housing recessed part 12 housing the antenna 4 is covered and secured by the securing part 16 of the bezel 15 attached to the wristwatch case 1, impact of dropping or the like can be received by the securing part 16. By this, the cover member 14 can be protected so it is not fractured by impact of dropping or the like.
