PROBLEM TO BE SOLVED: To secure excellent reception performance of an antenna in a built-in antenna electronic clock including a step motor, an anti-magnetic plate magnetically shielding the step motor and the antenna.SOLUTION: An electronic clock 100 comprises: an exterior case 80; an annular antenna body 40 that is housed in the exterior case 80; a time display part that is provided on an inner side of the antenna body 40, and includes a dial plate 11 and a pointer 13 rotatable centering around a pointer shaft 12; a substrate 25 that is housed in the exterior case 80; a driving mechanism 30 that is provided between the substrate 25 and the dial plate 11 and drives the time display part; a power supply pin 44 that electrically connects a power supply part 404 provided in the antenna body 40 to the substrate 25; and anti-magnetic plates S1 to S3 that are provided at a position of at least one of between the driving mechanism 30 and the dial plate 11 or between the driving mechanism 30 and the substrate 25. When viewed from a direction normal to the dial plate 11, the power supply pin 44 and the anti-magnetic plates S1 to S3 are not overlapped on each other. |
