In the present invention, prepared are: a mirror (31) that reflects solar light; a back surface reinforcing plate (35) that supports the back surface of the mirror (31); and a support frame (36) that is disposed at the back surface of the back surface reinforcing plate (35). Next, the back surface reinforcing plate (35) and the support frame (36) are joined. Then, an adhesive is disposed between the mirror (31) and the back surface reinforcing plate (35), and using a bottom mold (51) and a top mold (52), the mirror (31), the back surface reinforcing plate (35), and the support frame (36) are elastically deformed in a manner so that the reflecting surface of the mirror (31) forms a target 3D curved surface, and the elastically deformed state is maintained until the adhesive cures. |
