An ultrasonic sensor includes a sensor body, a cushion member, a retainer unit, and a drainage path. The sensor body includes an ultrasonic microphone and a microphone support unit which allows a protruding part of the ultrasonic microphone located at a distal end in an axial direction to protrude and supports the protruding part. The cushion member covers the protruding part. The retainer unit allows exposure of a portion of the cushion member that is located at the distal end in the axial direction, and a portion of the cushion member that is located at a proximal end in the axial direction is sandwiched between the retainer unit and an outer peripheral surface of the protruding part. The drainage path penetrates the retainer unit in a radial direction to allow water to be discharged out of the retainer unit from a gap between the retainer unit and the cushion member.
