A concentrating solar power generation apparatus (1) is provided with: light collecting lenses (11), which collect solar light; solar cell elements (20), which photoelectrically convert the solar light collected by means of the light collecting lenses (11); and placing substrates (21) respectively having the solar cell elements (20) placed thereon. The concentrating solar power generation apparatus is also provided with: a light collecting lens array (10), which is configured by disposing a plurality of the light collecting lenses (11) in the row direction (Dx) and the column direction (Dy); and a heat diffusion plate (30), which has a plurality of the placing substrates (21) placed thereon, and diffuses heat from the placing substrates (21). The heat diffusion plate (30) is disposed to face the light collecting lenses (11) disposed in the row direction (Dx), the size (SPx) of the heat diffusion plate (30), said size (SPx) being in the row direction (Dx), is equal to or more than double the size (SLx) of each of the light collecting lenses (11), said size (SLx) being in the row direction (Dx), and the size (SPy) of the heat diffusion plate (30), said size (SPy) being in the column direction (Dy), is smaller than the size (SLy) of each of the light collecting lenses (11), said size (SLy) being in the column direction (Dy). |
