PROBLEM TO BE SOLVED: To provide an AC magnetic curing instrument capable of providing higher curing effect without affected by casing.SOLUTION: An AC magnetic curing instrument includes a coil and a core material formed of magnetic material, and the core body includes at least two members, a first member and a second member. The first member has a near cylinder or prism-like post part. The coil is wound around a side wall of the post part. One top surface in the post part is configured to be closest to a treated body during usage. The top surface which is close to the treated body is a near semi-spherical recess. The second member is near spherical or a polyhedron. The polyhedron has twelve or more surfaces, and distances from the center to apexes are almost identical, with all angles being an obtuse angle. A part of the second member, in the recess of the first member, is exposed to the treated body side from the recess of the first member, and loaded in such a state as rotatable in the recess.COPYRIGHT: (C)2014,JPO&INPIT【課題】ケーシングの影響を受けることなく、より高い治療効果が得られる、交流磁気治療器を提供する。【解決手段】コイル及び磁性物質で形成されたコア材を備え、前記コア体は、少なくとも2つの部材、第1部材及び第2部材を備え、前記第1部材は略円柱または略多角柱の支柱部分を有し、該支柱部分の側壁周囲に前記コイルが巻かれ、前記支柱部分のうち一方の頂面が使用時に最も被処置体に近接するよう構成され、該被処置体に近接する方の頂面が略半球状の凹部となっており、前記第2部材は、略球体または多面体であり、前記多面体は12以上の面を有し、中心から各頂点までの距離が略一致し、全ての角が鈍角であり、前記第2部材は、前記第1部材の凹部内に、その一部が第1部材の凹部から被処置体側に露出し、該凹部内で自転可能な状態で装填されている、ことを特徴とする交流磁気治療器。【選択図】図2
