Abstract
An ultrasonic sensor comprises: an ultrasonic element that converts between an electric signal and ultrasonic vibration; and an element housing case having a bottomed tubular shape and housing the ultrasonic element therein. The element housing case includes a side plate portion having a tubular shape surrounding a directivity central axis, and a bottom plate portion that closes one end of the side plate portion in an axial direction parallel to the directivity central axis. The ultrasonic element is attached to the bottom plate portion. A part of the bottom plate portion inside an outline of the ultrasonic element when viewed along the directivity central axis includes a space formed due to a part of the part inside the outline being separated from the ultrasonic element.
