SOLAR CELL MODULE

PROBLEM TO BE SOLVED: To provide a solar cell module which achieves improved reliability.SOLUTION: A wiring material 30 includes: a wiring material body 31; first bonded parts 32; and second bonded parts 33. Each first bonded part 32 extends from the wiring material body 31 to the one solar cell 20 side of the solar cells located next to each other in a first direction x. The first bonded part 32 is bonded to the one solar cell 20 with a bond layer 40. Each second bonded part 33 extends from a portion 31a of the wiring material 31, to which the first bonded part 32 is connected, to the other solar cell 20 side of the solar cells located next to each other in the first direction x. The second bonded part 33 is bonded to the other solar cell 20 with the bond layer 40. A first opening 31a1, formed into a shape which does not have corners, is provided at the portion 31a of the wiring material body 31 to which the first and second bonded parts 32, 33 are connected.
