Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solar heat collector which is simple in structure and high in heat collecting efficiency when efficiently collecting solar energy.SOLUTION: When constituting a box body 11 composed of a heat insulating material, there is laid a heat collecting pipe 15 in which a thermal medium for receiving sunlight incident from an opening 12 at the bottom face 14 of the box body and converting it to heat circulates. The box body 11 has such a structure that light incident from the opening 12 is irradiated only on the bottom face 14. A side face 19 formed between the opening 12 and the bottom face 14 is tilted, and not irradiated with the light incident from the opening 12. The heat collecting pipe 15 is laid all over the bottom face 14. The opening 12 and the bottom face 14 are circular or polygonal. In a solar heat collector constituted as above, the light incident from the opening 12 is absorbed on the surface of the heat collecting pipe 15, and transmitted to the thermal medium 16 as thermal energy via the heat collecting pipe 15.
