PROBLEM TO BE SOLVED: To provide a heat collector capable of preventing disengagement of a clasp, receiving horizontal sun rays and reducing probabilities of intrusion of water or damages in an L-shaped bent part.SOLUTION: A heat collector 1 has a pipe 30 to allow a heat medium to flow inside and heats the heat medium by receiving solar light. The collector includes: an upper case 10 in a bottomed box shape that transmits solar light and has an open end; and a lower case 20 where the pipe 30 to allow the heat medium to flow is disposed, the lower case to be fitted inside the upper case 10. An open end 12 of the upper case 10 is fixed to the lower case 20 in such a manner that the open end is exposed to the outside and can deflect outwardly from the case. |
