1. A solar cell to be connected to another solar cell through a wiring member, the solar cell comprising:
- a photoelectric conversion body;
a plurality of fine-line electrodes formed on a main surface of the photoelectric conversion body; and
a connecting wire group formed on the main surface of the photoelectric conversion body and connected to the fine-line electrode, whereinthe connecting wire group has an expanding portion expanding from a connection region in the main surface to which the wiring member is to be connected, andthe expanding portion expands in an orthogonal direction orthogonal to a longitudinal direction of the wiring member in a state where the wiring member is connected to the connecting wire group.

Abstract
A solar cell (10) provided with connecting wires (351) which are connected to light receiving surface side fine-line electrodes (30A). The connecting wires (351) have expanding portions (BP1, BP2) which expand from the connection region (R1) where wiring member is to be connected. The expanding portions (BP1, BP2) expand in an orthogonal direction orthogonal to the longitudinal direction of the wiring material in a state where the wiring member is connected to the connecting wires (351).
