PROBLEM TO BE SOLVED: To provide a thermotherapy implement, preventing the occurrence of leakage of heat storage material filling the interior thereof to the outside and achieving a long time use. SOLUTION: In this thermotherapy implement, a thermoplastic synthetic resin sheet 3 is interposed between two sheets 2, 2 and stacked; a mesh cloth piece 4 is superposed on one sheet 2 of the two sheets 2, 2, and the overlapping parts of these sheets are bonded by fusion of the synthetic resin sheet 3 and the mesh cloth piece 4 caused by thermal solvent welding. The heat storage material storing part 5 partitioned by bonding caused by fusion of the synthetic resin sheet 3 between the two sheets 2, 2 is filled with the heat storage material 6.
