PROBLEM TO BE SOLVED: To solve an issue of an existing electrochemical analysis electrode that accurate measurement of the concentration of a measurement target object is impossible since the electrode can be in contact with material near the electrode alone of the electrochemically active material flowing in a porous body.SOLUTION: In an electrode 52, an analysis target sample containing electrochemically active material related to a measurement target material is connected to a porous material 20 moving by capillarity, and makes an oxidation-reduction reaction with the material. The electrode 52 has a protrusion 55 penetrating the porous material 20.SELECTED DRAWING: Figure 2 【課題】従来の電気化学的分析用電極は、多孔質内を流れる電気化学的に活性な物質のうち電極側に位置していたものとしか接触できず、正確な測定対象物の濃度を測定することができないという課題があった【解決手段】測定対象物に関連し、電気化学的に活性な物質を含む分析対象試料が、毛細管現象により移動する多孔質２０に接続されてその物質と酸化還元反応を行う電極５２であって、電極５２は、多孔質２０を貫通するように形成された突起部５５を有する。【選択図】図２
