Abstract
An ultrasound sensor for a vehicle has a housing which is fixedly arranged at a vehicle inner side of a periphery member of the vehicle, an ultrasound vibrator for sending and receiving ultrasound, and an ultrasound transferring member which is constructed of a different material from that of the housing to have an acoustic impedance with a medium value between an acoustic impedance of the ultrasound vibrator and that of the periphery member. The ultrasound vibrator is accommodated in the housing and fixed to an end portion of the housing, which faces the periphery member. The ultrasound transferring member is arranged at the end portion of the housing, and contacts both the ultrasound vibrator and the periphery member of the vehicle.
