PROBLEM TO BE SOLVED: To provide an electronic apparatus such as a watch capable of efficiently generating power by solving problems in appearance caused by dividing lines of solar cells or the like and without using a special IC of high cost.SOLUTION: A solar cell 12 for power generation as power generation means and a solar cell 13 for boosting as a power source of a booster circuit are created within the same solar cell, output V2 generated by connecting these solar cells in series is used as a power source of the booster circuit and output V1 generated by the solar cell 12 for power generation is boosted and supplied as a power source of a watch system part 31. Furthermore, the solar cell 12 for power generation is created so as to have a power generation area larger than that of the solar cell 13 for boosting, and the solar cell 13 for boosting is disposed at a position that is not conspicuous, such as a center hand. |
