Abstract: An electronic device includes a cylindrical case, a display, an annular light-transmitting parting member, an annular solar cell and an annular elastic member. At least the upper end of the case is open. The display is disposed in the case and exposed to a side where the upper end is located. The parting member is annular along the inner circumferential surface of the case. The annular solar cell is disposed under the parting member. The elastic member fixes the outer edge of the annular solar cell.

Abstract: An electronic device includes a solar cell, a wiring board, a connector, a first circuit, a second circuit and a fixing member. The wiring board includes a feeder wiring connected to the solar cell. The connector is continuous with the wiring board and includes a feeder electrode electrically connected to the feeder wiring. The first circuit includes a first electrode and a first wiring continuous with the first electrode. The second circuit includes a second electrode and a second wiring continuous with the second electrode. The fixing member fixes the feeder electrode, the first electrode and the second electrode in a state in which the electrodes are superposed on top of one another, to electrically connect each one of the electrodes to another one or more of the electrodes.

Abstract: An electronic device includes: a date indicator that includes a letter part and a non-letter part different from the letter part, the non-letter part being a through hole; and a solar battery disposed below the date indicator.

Abstract: A battery holding device includes a battery holding member and a plate. The plate houses the battery holding member. The battery holding member includes a fastener and a battery holder. The fastener is fixed to the plate. The battery holder holds a battery, and is arranged at a position where the battery holder does not contact the plate.
