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).
