An electronic timepiece with a solar cell includes a timepiece movement, a timepiece case for housing the timepiece movement, a casing ring for housing and holding the timepiece movement in the timepiece case, a solar cell and a dial. The solar cell is disposed almost vertically to a solar cell positioning portion provided in the casing ring, and the solar cell has a slender strip shape formed on a flexible substrate. Consequently, the solar cell is not disposed in the timepiece movement, and it is only necessary to change the casing ring as an external component even when a panel cover diameter is changed. Further, a solar cell can be coiled to match the size of the casing ring when it is incorporated in the casing ring, so that a common solar cell can be used despite a change in the panel cover diameter of the timepiece.
