In the case of a thin film solar cell having a glass substrate e, as shown in FIG. 6, since light was incident from the glass substrate 6 side, the photovoltaic force could be taken out from the back side of the light-receiving surface. Generally, the circuit section 9 of an electronic device is installed on the back side of the light-receiving surface, so that the circuit section and the output terminal A can be easily connected by crimping using the leaf spring 8 or the like.

However, as shown in Figure 7, the element light-receiving surface and the output terminal are on the same plane, so
It was not possible to extract the photovoltaic force from the back side of the light-receiving surface, and all lead wires had to be connected to guide it.
