Abstract
An electronic watch includes a time display, an antenna, a first substrate including a light-emitting element, a second substrate including a light-receiving element, a gear including a through hole passing light from the light-emitting element therethrough, the gear being disposed between the first and second substrates, and first and second conduction members electrically coupling the first and second substrates. The second substrate includes a first wiring electrically coupled to the first substrate via the first conduction member, and a second wiring electrically coupled to the second substrate via the second conduction member. Halfway on at least one of the first and second wirings, a circuit element is coupled in series that, compared to electrical resistance when a direct current flows in the wiring, increases electrical resistance when an alternating current generated by a radio wave received by the antenna flows in the wiring.
