PROBLEM TO BE SOLVED: To provide an inexpensive biostimulation electrode.SOLUTION: A first electrode includes: a pointed part that has a sharply-peaked tip end for stimulating epidermis of a living body a foot part 17 that is formed on a side longitudinally opposite to the pointed part and a locking part 19 that is formed in the form of projecting in a width direction. A second electrode includes: a cylindrical part 27 that has a tip end provided with a contact part for coming into line-contact or surface-contact with the epidermis of the living body and foot parts 28 that are arranged on a side opposite to the contact part in the form of extending from the cylindrical part 27. An insulation member is provided with a first through-hole 91 and second through-holes 93 that fix the first electrode and second electrode. A flexible wiring board is arranged on an insulation member surface where the first electrode and the second electrode are arranged. The foot part 17 of the first electrode penetrates the wiring board and is fixed to the first through-hole 91 of the insulation member by being pressed to the locking part 19, and the foot parts 28 of the second electrode pass through the wiring board and are fixed to the second through-holes 93 of the insulation member by being pressed to the cylindrical part 27.COPYRIGHT: (C)2014,JPO&INPIT【課題】安価な生体刺激電極を提供する。【解決手段】第1の電極は、生体の表皮を刺激する先端が鋭角に形成された尖頭部と、尖頭部と長手方向の反対側に形成された足部17と、幅方向に突出して形成された係止部19とを有する。第2の電極は、生体の表皮に線又は面で接触する接触部が先端に形成された円筒部27と、当該円筒部27から接触部の反対側に延設された足部28を有する。絶縁部材は、第1の電極と第2の電極を固定する第1の貫通孔91と第2の貫通孔93が形成さている。絶縁部の第1の電極、第2の電極が配設される側の面にフレキシブルな配線基板が配設され、第1の電極の足部17が、配線基板を貫通して絶縁部材の第1の貫通孔91に、係止部19まで圧入することで固定され、第2の電極の足部28は、配線基板を通過して絶縁部材の第2の貫通孔93に、円筒部27まで圧入することで固定される。【選択図】図9
