A solar cell module includes: a first optical system which concentrates sunlight; a power generation element which performs photoelectric conversion; a glass plate which supports the power generation element; and a second optical system which is on a light-exiting side of the first optical system and supports the glass plate. The second optical system includes a positioning portion, and a second lens on the first optical system side, and the glass plate is disposed at the positioning portion to position the power generation element at a focal point of the second lens.
