PROBLEM TO BE SOLVED: To provide a biological signal detection device capable of instructing a processing under the consideration of effectiveness of detected biological signals when performing the processing using the biological signals.SOLUTION: A biological signal detection device 5 includes: a biological signal sensor part 11 detecting a biological signal of a person on a vehicle； a travelling condition sensor part 12 detecting a travelling condition of the vehicle； and a biological signal output part 15. When a vehicle traveling condition corresponding to a prescribed period of the biological signal is in a condition having high reliability, the biological signal output part 15 outputs the biological signal in the prescribed period and the high reliability. When the vehicle traveling condition corresponding to the prescribed period of the biological signal is in a condition having low reliability, the biological signal output part 15 outputs the biological signal in the prescribed period and the low reliability.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】生体信号を用いた処理を行う場合に、検知された生体信号の有効性を加味した処理を指示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５は、車両の搭乗者の生体信号を検出する生体信号センサ部１１と、車両の走行状態を検出する走行状態センサ部１２と、生体信号出力部１５とを備える。生体信号の所定の期間に対応する車両の走行状態が信頼度の高い状態の場合、生体信号出力部１５は、所定の期間の生体信号と高い信頼度とを出力する。生体信号の所定の期間に対応する車両の走行状態が信頼度の低い状態の場合、生体信号出力部１５は、所定の期間の生体信号と低い信頼度とを出力する。【選択図】図１
