PROBLEM TO BE SOLVED: To provide a bioelectrode which has achieved compatibility between comfortable fitness when worn and waterproofness.SOLUTION: This bioelectrode is provided with an electrode pad to be worn on a living body and a lead wire 110 connected to the electrode pad. The electrode pad includes: a waterproof base material 106 having an adhesive mounting surface and having a hole at the center a waterproof sealing member 105 fixing the lead wire 110 to the back of the mounting surface of the base material while covering the hole 1061, so as to allow a detecting electrode 104 provided at the distal end of the lead wire 110 to be exposed from the hole 1061 of the waterproof base material 106 and a conductive gel 103 provided on the mounting surface so as to be in contact with the detecting electrode 104.COPYRIGHT: (C)2013,JPO&INPIT【課題】良好な装着感と防水性を両立した生体電極を提供すること。【解決手段】生体に装着する電極パッドと、電極パッドに接続されるリード線110とを有する。また、電極パッドが、粘着性を有する装着面を有し、略中央に穴を有する防水性基材106と、リード線110を、その先端に設けられた検出電極104が防水性基材106の穴1061から露出するよう、穴1061を覆いながら基材の装着面の裏面に固定する、防水性シール部材105と、検出電極104に接するように装着面に設けられた導電性ゲル103とを有する。【選択図】図3
