Abstract:
    An ultrasonic sensor includes a sending element for sending an ultrasonic wave to an object to be detected, a receiving portion for receiving the ultrasonic wave reflected by the object, an oscillating portion that oscillates by the ultrasonic wave transmitted thereto, and a supporting portion for holding an end part of the oscillating portion. The receiving portion is exposed to a space where the object exists. The receiving portion and the oscillating portion are connected through the supporting portion such that the ultrasonic wave received by the receiving portion is transmitted to the oscillating portion through the supporting portion. The oscillating portion is separate from the receiving portion by the supporting portion.
