ABSTRACT:
An ultrasonic sensor includes an integral housing including a plurality of tubular containers that are open at one end and closed by bottom portions at the other end and have side portions extending from the one end to the other end, and at least one connecting portion that connects the plurality of tubular containers. Piezoelectric devices are disposed on respective inner bottom surfaces of the respective bottom portions of the plurality of tubular containers. Side portions of the tubular containers are connected to each other, through a connecting portion, at portions adjacent to bottom portions where the amount of displacement caused by the vibrations of piezoelectric devices is smallest.
