Abstract: A solar cell module includes: a solar cell; a light reflector above a surface of the solar cell or around the solar cell, the light reflector being elongated and including a light reflective film and an insulating component; a protective component that covers the surface of the solar cell; and an encapsulant between (i) the solar cell and the light reflector and (ii) the protective component. The light reflective film has an uneven structure in which a recessed portion and a protruding portion are repeated in a direction crossing a longitudinal direction of the light reflector, and a tangential direction of at least part of a ridge line of the protruding portion and the longitudinal direction intersect when the solar cell is seen in a plan view.
