Abstract
An ultrasonic sensor includes an ultrasonic detector for detecting an ultrasonic wave, an acoustic matching member joined to the ultrasonic detector, a housing in which the ultrasonic detector and the acoustic matching member are accommodated, a vibration isolator located between the acoustic matching member and an inner side wall of the housing to damp an unwanted vibration from outside, and a cushion member located between the ultrasonic detector and an inner bottom wall of the housing to absorb external force applied to the ultrasonic sensor The cushion member is not in contact with the acoustic matching member.
