PROBLEM TO BE SOLVED: To provide an elastic heat generation body which suitably follows the largely movable region of a human body, is excellently fitted to the body, especially, from the middle stage to end stage of use, and effectively shows the hyperthermic effect of the heat generation body and the efficacy.SOLUTION: The elastic heat generation body has a heat generation composite body where a heat generation material is held between non-elastic porous sheets. The heat generation composite body is joined with an elastic member to be superimposed on the composite body at a point sealing part arranged within the end edge of the composite body when viewing in plane. A non-joint superimposition part of the elastic member, which is superimposed on but not joined with the heat generation composite body, is elastic and independent from the heat generation composite body.COPYRIGHT: (C)2011,JPO&INPIT【課題】可動の大きな身体の部位に対して好適に追従し、特に使用中期から末期にかけての身体へのフィット性がよく、発熱体の温熱効果及びその効能を効果的に発揮させる伸縮性発熱体を提供する。【解決手段】非伸縮性の多孔質シートに発熱材が介在された発熱複合体を有する伸縮性発熱体であって、前記発熱複合体がこれと重合される伸縮性部材に平面視において前記複合体の端縁内に施されるポイントシール部で接合されており、前記伸縮性部材の前記発熱複合体と重合するが接合されていない非接合重合部は前記発熱複合体から独立して伸縮可能とされた伸縮性発熱体。【選択図】図1
