PROBLEM TO BE SOLVED: To provide an organism stimulating magnetic field generating device that can apply a strong magnetic field to an object part in a deep part of an organism.SOLUTION: An organism stimulating magnetic field generating device includes: an annular C-shape core 2 having a gap part G； and a coil 3 wound around the core 2. The core 2 includes: a pair of opposed extension parts 2c positioned on both sides of the gap part G and opposite to each other while extending in a direction in proximity to each other； and a pair of opposite side parts 2b provided side by side on respective outer sides of the pair of opposed extension parts 2c. The coil 3 is wound around each of the pair of opposite side parts 2b.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】生体深部の対象部位に高い磁場を印加することが可能な生体刺激用磁場発生装置を提供する。【解決手段】生体刺激用磁場発生装置は、ギャップ部Ｇを有するＣ環状のコア２と、コア２に巻回されたコイル３と、を備える。コア２は、ギャップ部Ｇの両側にあり互いに近接する方向に延在して対向する一対の対向延在部２ｃと、一対の対向延在部２ｃのそれぞれの外側に併設された一対の対辺部２ｂと、を有する。コイル３は、一対の対辺部２ｂのそれぞれに巻回されている。【選択図】図１
