To provide a drunk state detection device which can correctly detect a drunk state of a driver by suppressing erroneous detection.SOLUTION: A drunk state detection device S which is mounted on a vehicle and can detect a drunk state of a driver D, comprises: a thermographic camera 1 which is mounted in the vicinity of a driver seat and can detect the body temperature of the driver; a contact type electrocardiographic sensor 13 which is disposed in a steering wheel 5 that is steered by the driver and can detect the electrocardiographic waveform and the heart rate of the driver; a non-contact type gas detection sensor 10 which is disposed in a grip part 7 that is gripped by the driver in the steering wheel and can detect an alcohol component contained in the gas discharged from the skin of the driver in a state in non-contact with the skin; and a determination unit 20 which can determine the drunk state of the driver on the basis of the body temperature measurement value detected by the thermographic camera, the electrocardiographic waveform, and heart rate measurement value detected by the contact type electrocardiographic sensor and the alcohol component value detected by the gas detection sensor.SELECTED DRAWING: Figure 2 【課題】誤検知を抑制して、的確に運転者の飲酒状態を検知可能な飲酒状態検知装置を提供すること。【解決手段】車両に搭載されて、運転者Ｄの飲酒状態を検知可能な飲酒状態検知装置Ｓ。運転席付近に搭載されて運転者の体温を検知可能なサーモカメラ１と、運転者の操舵するハンドル５に配設されて運転者の心電波形と心拍数とを検知可能な接触式心電センサ１３と、ハンドルにおける運転者の把持するグリップ部７に配設されて、運転者の皮膚から排出されるガスに含まれるアルコール成分を皮膚と非接触の状態で検知可能な非接触式のガス検知センサ１０と、サーモカメラにより検知された体温測定値、接触式心電センサにより検知された心電波形と心拍数測定値、及び、ガス検知センサにより検知されたアルコール成分値、に基づいて、運転者の飲酒状態を判定可能な判定部２０と、を備える。【選択図】図２
