Abstract
An ultrasonic sensor is disclosed. The ultrasonic sensor includes a plurality of sensor elements arranged in an array. Each sensor element includes an ultrasonic sensing element and an acoustic matching member. The ultrasonic sensor further includes a bonding member having a thickness approximately equal to a space interval between adjacent ultrasonic sensing elements. The bonding member adhesively fixes the plurality of sensor elements, and includes a portion contacting each ultrasonic sensing element. An elastic modulus of the portion is smaller than that of each ultrasonic sensing element.
