PROBLEM TO BE SOLVED: To provide an electrode support mechanism and an electrostimulator, in which an electrode can be placed stably even in a blood vessel with a small diameter and many curved parts.SOLUTION: An electrode support mechanism (1) comprises: a plurality of long electrode support parts (2) which are made of an elastic body curved in a natural state and provided with electrode parts a distal end projection part (3) for gathering and fixing the distal ends of the plurality of electrode support parts into one a base end fastener (4) for gathering and accommodating the base ends of the plurality of electrode support parts into one and a wiring part (5) which is connected to the base end fastener and energizes the electrode parts. The base end fastener is arranged on an axis line of the wiring part. The distal end projection part is arranged at a position away from the axis line of the wiring part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】細径で湾曲部の多い血管内でも安定して電極の留置ができる電極支持機構及び電気刺激装置を提供すること。【解決手段】本発明に係る電極支持機構(1)において、自然状態で湾曲した弾性体からなり、電極部が設けられる複数の長尺な電極支持部(2)と、前記複数の前記電極支持部の先端を一つに集めて固定する先端突出部(3)と、前記複数の前記電極支持部の基端を一つに集めて収容する基端留め具(4)と、前記基端留め具に接続され、前記電極部に通電する配線部(5)と、を備え、前記基端留め具は、前記配線部の軸線上に配置され、前記先端突出部は、前記配線部の前記軸線から離間した位置に配置される。【選択図】図1
