PROBLEM TO BE SOLVED: To facilitate the burying work of a flexible fluid pipe for heat medium and reduce the generation of uncomfortable sound or collision sound when heat medium is passed through the flexible fluid pipe for heat medium by a method wherein the flexible fluid pipe for heat medium, buried in the internal space of a groove, is retained surely. SOLUTION: In a heat radiating board 10 for floor heating, consisting of a flat plate type base body, a plurality of parallel grooves 11 and a curved grooves for connecting the end parts of these parallel grooves 11 are engraved in one surface of the same while these grooves are formed so as to have U-shaped sectional configuration orthogonal to the lengthwise direction of these grooves. In this case, a plurality of projected parts 12, 12', which are projected slightly toward the space of the groove from the inner wall surface of the same, and/or a plurality of recessed parts, recessed slightly from the inner wall surface of these grooves, are provided at proper positions on the inner wall surfaces of the grooves. |
