PROBLEM TO BE SOLVED: To provide a biological information detecting device capable of stably detecting biological information of an occupant, such as respiration even when a strain sensor, for example, having a high detection ability is used in order to acquire precise biological information.SOLUTION: The biological information detecting device includes: a sensor 17 for detecting biological information and first and second support members 23A and 24 having elasticity and supporting the sensor 17 by holding it between them. The second support member 24 has contact with a biological information origination source on the front surface and with the sensor 17 on the rear surface. The elasticity level of the second support member 24 is set to allow the settlement amount of a pressurization member in a predetermined shape when the second support member 24 is pressurized with the pressurization member by predetermined pressurization force P1 to be smaller than the settlement amount of the pressurization member when the first support member 23A is pressurized with the pressurization member by the pressurization force P1.COPYRIGHT: (C)2013,JPO&INPIT【課題】精度の高い生体情報を得るために高検出能力を有する例えば歪みセンサを用いた場合にも安定して呼吸等の乗員の生体情報を検出可能な生体情報検出装置を提供する。【解決手段】生体情報を検出するセンサ17と、センサ17を挟んで支持する弾性を有する第1および第2の支持部材23A、24と、を備え、第2の支持部材24は表面で生体情報発信源と接触し、裏面でセンサ17と接触し、第2の支持部材24を所定形状の押圧部材で所定の押圧力P1で押圧したときの押圧部材の沈下量が、第1の支持部材23Aを押圧部材および押圧力P1で押圧したときの押圧部材の沈下量よりも小さくなるよう第2の支持部材24の弾性度が設定される。【選択図】図1
