Problem to be solved: to provide a living body information measuring apparatus capable of easily attaching a portion for inputting living body information from a living electrode to a portion including an electrode for organism contacting the organism.The biometric information measuring apparatus includes an electrode portion 100 including a biological electrode E101 and E102, and a mounting portion 200 detachably attached to the electrode portion 100. The electrode portion 100 includes first terminals T101 and T102 connected to the electrode electrodes 101 and 102, and first magnetic members M101 to M104. The mounting section 200 includes second terminals t201 and T202 for inputting biological information and second magnetic members M201 to M204.The arrangement of the mounting portion 200 relative to the electrode portion 100 draws the mounting portion 200 and the electrode part 100 by the magnetic force between the first magnetic members M101 to M104 and the second magnetic members M201 to M204 when the first terminals 101 and 102 and the second terminals 201 and 202 are made conductive Fit.Diagram【課題】生体に接触した生体用電極を含む部分に対して、生体用電極から生体情報を入力する部分を容易に取り付けることができる生体情報測定装置を提供する。【解決手段】生体情報測定装置は、生体用電極E101,E102を含んだ電極部100と、電極部100に着脱自在に取り付けられる取付部200とを有する。電極部100は、生体用電極E101,102に接続される第1端子T101,T102と、第1磁性部材M101~M104とを含む。取付部200は、生体情報を入力するための第2端子T201,T202と、第2磁性部材M201~M204とを含む。電極部100に対する取付部200の配置が、第1端子101,102と第2端子201,202とを導通させる配置の場合に、第1磁性部材M101~M104と第2磁性部材M201~M204との間の磁力によって取付部200と電極部100とが引き合う。【選択図】図1
