To provide a magnetic treatment tool in which a magnet is accurately arranged inside a soft cord-like body, and which can exhibit stable effect of magnetic force, and makes the soft cord-like body be hardly torn.SOLUTION: A magnetic treatment tool comprises a soft cord-like body extending in the longitudinal direction, and a magnet stored inside the soft cord-like body. The magnetic treatment tool is such that: the soft cord-like body is a joined body formed by joining a first cord-like member having a trapezoidal groove on an outer peripheral surface and extending in the longitudinal direction, and a second cord-like member having a trapezoid projection corresponding to the trapezoidal groove of the first cord-like member; the first cord-like member has a recessed magnet support part formed in a recessed shape in a bottom of the trapezoidal groove; at least a part of the magnet is inserted into the recessed magnet support part; and an angle θa made by virtual lines connecting a center point of the soft cord-like body to upper end parts at both sides of the trapezoidal groove of the first cord-like member is in a range of 40 degrees or more and 150 degrees or less.SELECTED DRAWING: Figure 5【課題】軟質性紐状体の内部に磁石が精度よく配置されていて、安定した磁力の効果を発揮することができ、かつ軟質性紐状体が裂けにくい磁気治療具を提供する。【解決手段】長手方向に延びた軟質性紐状体と、前記軟質性紐状体の内部に収容されている磁石とを有する磁気治療具であって、前記軟質性紐状体は、外周面に台形溝を有する長手方向に延びた第1紐状部材と、前記第1紐状部材の前記台形溝に対応する台形突起を有する第2紐状部材とを接合した接合体であり、前記第1紐状部材は、前記台形溝の底部に凹状に形成された凹状磁石支持部を有し、前記磁石の少なくとも一部が前記凹状磁石支持部に挿入されていて、前記軟質性紐状体の中心点と、第1紐状部材の台形溝の両側上端部とを結ぶ仮想線がなす角度θaが40度以上150度以下の範囲にある磁気治療具。【選択図】図5
