PROBLEM TO BE SOLVED: To provide a solar light collector capable of being miniaturized by shortening a focal length. SOLUTION: This solar light collector is provided with a collector 1 having a reflecting face formation layer 4 as a reflecting face 5 on one face of a transparent body of which one face has a cross-section of roughly parabolic shape and of which the other face opposite to the face is composed of a straight line or a curved line bulging in the direction separating from the roughly parabolic shape only at its peripheral section, and made of a transparent substance, and having a solar light incidence plane on the other face, the solar light from the incidence plane is reflected by the reflecting face, and the reflected light is refracted from the incidence plane and emitted to the external, thus a focal length of the emitted light can be shortened.
