<P>PROBLEM TO BE SOLVED: To solve a problem with an electronic timepiece having a solar cell having flexibility for arranging it substantially perpendicular to the dial on the outer periphery of the movement of the electronic timepiece to supply electric power to the electronic timepiece, wherein, when the solar cell is divided into a plurality of photovoltaic power generation cells in the long side direction and they are connected in series, and the electronic timepiece is put on an arm, it is partially shaded by clothes, an photovoltaic power generation cell which does not contribute to power generation occurs, and sufficient charge is not obtained. <P>SOLUTION: An photovoltaic power generation cell of the solar cell is equally divided into two parts in the long side direction, one of the two divided photovoltaic power generation cells is arranged in the 12:00 direction, the other is arranged in the 6:00 direction, and both divided photovoltaic power generation cells are interconnected electrically. <P>COPYRIGHT: (C)2009,JPO&INPIT |
