PROBLEM TO BE SOLVED: To provide a muscle electrostimulator capable of efficiently giving an electric stimulation to a movement point of a muscle.SOLUTION: A muscle electrostimulator 1 for giving an electric stimulation to a muscle comprises: a body part 10 a power supply part 20 housed in the body part 10 a sheet-shaped base material 33 an electrode part 30 for generating the electric stimulation and a gelatinous pad 35. The pad 35 has adhesiveness and electric conductivity and covers the electrode part 30. The electrode part 30 includes: a first electrode group 31 including a plurality of electrodes 311, 312, 313 to which voltages having the same polarity are to be applied and a second electrode group 32 including a plurality of electrodes 321, 322, 323 to which voltages having the polarity reverse to that of the voltages applied to the first electrode group 31 are to be applied. The pad 35 includes: a first pad 351 for covering the plurality of electrodes 311 to 313 included in the first electrode group 31 in a lump and a second pad 352 for covering the plurality of electrodes 321 to 323 included in the second electrode group 32 in a lump.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】筋肉の運動点に効率的に電気刺激を付与することができる筋肉電気刺激装置を提供すること。【解決手段】筋肉電気刺激装置1は筋肉に電気刺激を付与するためのものであって、本体部10と、本体部10に収納された電源部20と、シート状の基材33と、電気刺激を発生させる電極部30と、ゲル状のパッド35とを備える。パッド35は粘着性及び導電性を有し、電極部30を覆っている。電極部30は、同一極性の電圧が印加される複数の電極311、312、313を含む第1電極群31と、第1電極群31に印加される電圧と反対の極性の電圧が印加される複数の電極321、322、323を含む第2電極群32とを含む。パッド35は、第1電極群31に含まれる複数の電極311~313を一括して覆う第1パッド351と、第2電極群32に含まれる複数の電極321~323を一括して覆う第2パッド352とを含む。【選択図】図2
