The entire surface of a light-receiving plate (9), which floats on the surface of tin (8) serving as a low-melt heat medium and receives solar rays (L), is made of a solid carbon material coated with a silicon carbide film (11), so the surface has the black color of the silicon carbide film (11) and exhibits a high rate of absorption of solar rays (L). Furthermore, because at least the surface of the light-receiving plate (9) is formed using the silicon carbide film (11), heat resistance is excellent. |
