A solar cell module including two or more adjacent solar cells (1a, 1b), a connection member (2) for electrically connecting the solar cells (1a, 1b) to each other, and a solder layer (5) disposed between the solar cells (1) and the connection member (2), wherein first and second opening holes (4a, 4b) are formed at a connection portion of the connection member (2) corresponding to the first and the second solar cells (1a, 1b), the first and the second opening holes (4a, 4b) are configured that solder is deposited into them, and first and second protruding parts (3a, 3b) are formed at a part of the outer periphery of each of the first and second opening holes (4a, 4b) of the connection member(2). By the present invention, it is possible to ensure sufficient thickness of the solder joining layer and to improve reliability for long-term use.
