PROBLEM TO BE SOLVED: To provide a biological information detection sensor for substantially securing a surface distance and a spatial distance (namely achieving defibrillation protection) and capable of being reduced in its size.SOLUTION: A biological information detection sensor comprises: plural first substrates 21a-21awhich are arranged in plural stages a second substrate 22 first connection parts 21c for electrically connecting the first substrates which are adjacent out of the plural first substrates 21a-21a and insulation members 23. Each of the plural first substrates 21a-21acomprises a pressure-proof resistance 26 to which a biological information detection part is electrically connected. The second substrate 22 has a circuit for processing the biological information which is input from the biological information detection part through the pressure-proof resistance 26, and each of the insulation members 23 is provided between the first substrates which are adjacent out of the plural first substrates 21a-21a.SELECTED DRAWING: Figure 9【課題】沿面距離及び空間距離を実質的に確保しつつ(すなわち、除細動保護を実現しつつ)小型化を実現することができる生体情報検出センサを提供する。【解決手段】多段配置された複数の第1基板21a1~21a3と、第2基板22と、前記複数の第1基板21a1~21a3のうち隣接配置された第1基板間を電気的に接続する第1接続部21cと、絶縁部材23と、を備え、前記複数の第1基板21a1~21a3には、それぞれ、生体情報検出部が電気的に接続される耐圧抵抗26が実装され、前記第2基板22には、前記生体情報検出部から前記耐圧抵抗26を介して入力される生体情報を処理する回路が実装され、前記絶縁部材23は、前記複数の第1基板21a1~21a3のうち隣接する第1基板間に配置された生体情報検出センサ。【選択図】 図9
