Abstract
An ultrasonic sensor is provided with an ultrasonic element that converts between an electrical signal and an ultrasonic vibration and an element accommodating case having a bottomed cylindrical shape and accommodating the ultrasonic element inside thereof. The element accommodating case includes a side plate portion formed in a cylindrical shape that surrounds a directional center axis, and a bottom plate portion that closes one end side of the side plate portion in an axial direction which is parallel to the directional center axis. The ultrasonic element is attached to the bottom plate portion. The bottom plate portion includes at least one protrusion. The protrusions vibrate together with the bottom plate portion when the bottom plate portion vibrates as an ultrasonic vibration.
