Zusammenfassung:	According to an embodiment of the present invention, a device for measuring an alcohol component, comprises: an inlet for separately absorbing exhalations of a driver and a passenger; a sensor for detecting an alcohol component in at least one of the exhalations of the driver and the passenger; a driver valve and a passenger valve to be controlled to be opened or closed to allow the exhalations of the driver and the passenger to be introduced to the sensor, respectively; and a control unit for determining whether the passenger is in the vehicle, and controlling opening or closing of the driver valve and the passenger valve in accordance with a determination result. Accordingly, breathing of a driver and breathing of a passenger can be distinguished, and the influence of the passenger in detecting an alcohol component in breathing of the driver is removed to accurately determine a drinking status of the driver. 본 발명의 일 실시예에 따른 알코올 성분 측정 장치는 운전자의 호기 및 동승자의 호기를 각각 흡수하는 인렛과, 상기 운전자의 호기 및 상기 동승자의 호기 중 적어도 어느 하나 이상의 호기 내 알코올 성분을 검출하는 센서와, 상기 운전자의 호기가 상기 센서로 유입되도록 열림 제어 또는 닫힘 제어되는 운전자 밸브 및 상기 동승자의 호기가 상기 센서로 유입되도록 열림 제어 또는 닫힘 제어되는 동승자 밸브 및 상기 동승자의 탑승 여부를 판단하고, 판단 결과에 따라 상기 운전자 밸브 및 상기 동승자 밸브의 열림 또는 닫힘을 제어하는 제어부를 포함하여, 운전자의 호흡과 동승자의 호흡을 구별하고, 운전자의 호흡 내 알코올 성분을 검출하는데 있어 동승자의 영향을 제거하여 운전자의 음주 상태를 정확하게 판단할 수 있다.
