    • PROBLEM TO BE SOLVED: To freely establish a size of a solar heat collector pipe in accordance with the scale of a building by permitting a portion of the outer periphery of the pipe to form an elongated outer cylinder made of a transparent resin and integrally providing its inside with a radiating fin in a longitudinal direction. SOLUTION: A solar heat collector pipe 2 consists of an outer cylinder 3 having a rectangular cross section and a lattice like heat collecting fin 8 which is provided inside of the outer cylinder. The outer cylinder 3 comprises a U-shaped housing 5 consisting of a bottom side 5a and left and right sides 5b, and made of black vinyl chloride resin. A transparent side 4, i.e., a flat plate made of acrylic resin, is provided at an upper side of the rectangular shape to cover the opening of the housing 5. The upper portions of the sides 5b of the housing 5 are formed with engaging recesses 5c with their openings being positioned in face-to-face relation. Both ends of the transparent side 4 are inserted into the engaging recesses 5c so as to be detachable. The solar heat collector pipe 2 is made of a resin and has the same structure at any portion thereof in the longitudinal direction. Thus, by only cutting into an appropriate length, the solar heat collector pipe 2 of a desired length can be manufactured.
