The present invention prevents the separation of conductive particles from a tab wire and an electrode regardless of binder performance. The present invention is provided with: a plurality of solar cells (2); and tab wires (3) that are adhered via a thermoset conductive adhesive (17) including conductive particles onto electrodes (11, 13) that are respectively formed on the front surfaces of the solar cells (2) and the back surfaces of adjacent solar cells (2) to connect pairs of solar cells (2). The conductive adhesive (17) includes solder particles (23). The solder particles (23) have a multi-layer structure constituted from at least an inner layer (24) and an outer layer (25), wherein the melting point of the solder forming the inner layer (24) is higher than the melting point of the solder forming the outer layer (25). |
