PROBLEM TO BE SOLVED: To provide a biological signal detection device that can improve power distribution of a conductive member and a scalp of a user so as to perform stable measurement for a long time.SOLUTION: In the biological signal detection device, a plurality of drought-resistant electrolytic solution soaking parts 3 which are formed to have thickness allowing contact with a scalp without interposing hair between the drought-resistant electrolytic solution soaking parts and the scalp are connected to a conductive electrode element 2 so that front ends of the drought-resistant electrolytic solution soaking parts 3 are easily contacted to the scalp. Also, stable measurement for brain waves can be performed for a long time by suppressing evaporation of a liquid having conductivity.COPYRIGHT: (C)2012,JPO&INPIT【課題】導電部材と頭皮の通電状態を良好にして、長時間、安定した測定を行うことが可能な生体信号検出装置を提供する。【解決手段】頭髪を挟むことなく頭皮に到達できる程度の太さに形成された耐乾性電解液染込部3が導電性の電極素子2に複数接続されることにより、耐乾性電解液染込部3の先端を頭皮に容易に接触させることができ、また導電性を有する液の蒸発を抑えることができるので、長時間、安定した脳波測定を行うことができる。【選択図】図1
