PROBLEM TO BE SOLVED : to the body by a simple operation, and due to the synergistic effect of the negative ion radiation hormesis comfortable effect can be exerted on the body of the negative ion generating low-radiation. SOLUTION : as a minus ion generator and silicon-based ceramic material and the radioactive rare earth element as the radiation generating material containing a mixture of mineral low radioactive minus ion generating composition is uniformly dispersed in the resin base 13 is formed into a prescribed shape and a surface of one of the, showing on the skin adhesive tacky surface layer 12 is formed, a tacky surface layer 12 is covered with a release paper minus ion generating sheet 10A having low emissivity. By removing the release paper F attached to any part of the body. Selected drawing : fig. 3
