Abstract: A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.
