PROBLEM TO BE SOLVED: To provide a biological signal detection device capable of reliably detecting a user's biological signal and reducing a burden on the user.SOLUTION: A biological signal detection device 1 comprises: a retention part 5 fitted to a living body； a first detection part 91 and a second detection part 92 which are retained by the retention part 5 and measure a user's biological signal； and a driving part 17 which moves the first detection part 91 and the second detection part 92. The first detection part 91 and the second detection part 92 switch from one of a state where at least one of them is in contact with the living body and a state where the other detection part is not in contact with the living body to the other state.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】使用者の生体信号を確実に検知するとともに、使用者の負担を軽減することができる生体信号検知装置を提供する。【解決手段】生体信号検知装置１は、生体に装着される保持部５と、保持部５に保持され、使用者の生体信号を計測する第１検知部９１及び第２検知部９２と、第１検知部９１及び第２検知部９２を移動させる駆動部１７とを備えている。第１検知部９１及び第２検知部９２は、少なくとも１つが生体に接触する状態と、及び、残りの検知部が生体に非接触となる状態の一方から他方に切替える。【選択図】図２
