PROBLEM TO BE SOLVED: To provide an outer ear canal inserting type electrode in which sense stimulating current directly passes in an outer ear canal in a vestibula electric stimulation method further the influence of noise can be reduced in a brain wave measuring method without troublesome of attaching and detaching and uncomfortable feeling due to the attachment of gel or paste to a skin.SOLUTION: The outer ear canal inserting type electrode has an elastic body deforming according to the shape of the outer ear canal, an electroconductive layer covering at least a part of the surface of the elastic body and electrically connected to conductive wires, an electroconductive soft layer 130 covering the surface of the electroconductive layer, having an electric resistivity higher than that of the electroconductive layer, and deforming according to the shape of the outer ear canal and is characterized in that the outer peripheral surface of the outer canal inserting type electrode 100 comes in contact with the inner peripheral surface of the outer ear canal and electrically comes into contact with the outer ear canal by the contacting pressure.COPYRIGHT: (C)2012,JPO&INPIT【課題】着脱の煩わしさやゲルやペーストの皮膚への付着による不快感なしに、前庭電気刺激手法において、感覚刺激電流が直接外耳道内に流れ、また、脳波計測手法において、雑音の影響を軽減できる外耳道挿入型電極を提供する。【解決手段】外耳道の形状に合わせて変形する弾性体と、弾性体表面の少なくとも一部を覆い、導線に電気的に接続される導電層と、導電層表面を覆い、導電層よりも電気抵抗率が高く、外耳道の形状に合わせて変形する導電性柔軟層130と、を備え、外耳道挿入型電極100の外周面が外耳道内周面に接し、その接触圧で外耳道に電気的に接触する、ことを特徴とする。【選択図】図2
