Abstract
An ultrasonic sensor includes a piezoelectric element and an acoustic matching member that are joined together to form an ultrasonic detector base. The ultrasonic detector base is sectioned by a clearance extending in an ultrasonic propagation direction to form multiple ultrasonic detectors arranged in an array. The clearance does not entirely section the ultrasonic detector base so that the ultrasonic detectors are joined together by a portion of the ultrasonic detector base.
