PROBLEM TO BE SOLVED: To provide a magnetic therapeutic instrument that is easily attached/detached and lightweight, that gives no sense of oppression to an attached part, and that can be worn fittingly to the attached part.SOLUTION: The present invention refers to the magnetic therapeutic instrument 1 capable of varying the shape in a manner that fits to a prescribed part of the body, and is also capable of maintaining the varied shape. The instrument 1 includes: a narrow and long first rubber-like elastic body 10 a core material 20 for maintaining a shape, a material that is arranged along the longitudinal direction of the first rubber-like elastic body 10 and that is composed of synthetic resin having a higher shape maintenance capacity than polycarbonate and a magnetic material 30 that is contained in the first rubber-like elastic body 10 for the purpose of exerting a magnetic force on the body.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】 着脱が容易でかつ軽量であり、また、装着部位に圧迫感を与えることがなく、当該装着部位にフィットした状態で装着することができる磁気治療具を提供する。 【解決手段】 本発明は、身体の所定部位に沿うように形状を変化させることが可能であるとともに当該形状を変化させたときの形状保持が可能な磁気治療具1であって、細長い形状の第一ゴム状弾性体10と、第一ゴム状弾性体10の長手方向に沿って配設されており、ポリカーボネートよりも形状保持能力の高い合成樹脂でなる形状保持用の芯材20と、身体に磁力を及ぼすように第一ゴム状弾性体10に含まれる磁性材30と、を備える磁気治療具1に関する。【選択図】図1
