Abstract
An ultrasonic sensor, which can prevent a breakdown caused by the infiltration of water from the outside occurring due to the jet of high-pressure wash water or the like without the deterioration of the sensitivity of an ultrasonic transducer within the range of the fixing-clamping caused by an elastic member, is obtained. The ultrasonic sensor includes a cylindrical sensor case, an ultrasonic transducer that is disposed close to an opening face in the sensor case and includes a vibration surface, and an elastic member that is provided between the ultrasonic transducer and the sensor case and covers a side surface and a bottom of the ultrasonic transducer. An exposed surface end of the elastic member close to the opening face is formed to be thinner than a portion of the elastic member that covers the side surface of the ultrasonic transducer.
