Zusammenfassung:A concentrator photovoltaic module includes: a concentrating portion configured by arranging a plurality of Fresnel lenses that concentrate sunlight; a plurality of power generating elements arranged at positions corresponding respectively to the plurality of Fresnel lenses; a plurality of ball lenses that are provided corresponding respectively to the plurality of power generating elements and guide the sunlight concentrated by the plurality of Fresnel lenses to the plurality of power generating elements; and a housing that contains the plurality of ball lenses and the plurality of power generating elements. The housing includes a resin frame body, and a metal bottom plate that is fixed to the frame body, and on the inner surface of which the plurality of ball lenses and the plurality of power generating elements are arranged. The groove portion (30) for reducing thermal expansion of the inner surface (15a) side of the bottom plate is provided on the inner surface (15a) of the bottom plate.
