An attachment member (1) has a through hole (11). An ultrasonic sensor (2) is fixed to the attachment member (1) in such a manner that an emitting surface (22) of the ultrasonic sensor (2) is exposed from the through hole (11) of the attachment member (1). A vibration propagation preventing layer (3) is interposed between the entire periphery of a side surface of the ultrasonic sensor (2) and a wall surface of the through hole (11) of the attachment member (1). Vibration plates (41) and (42) are disposed on one of a first straight line passing through the center point of the emitting surface (22) of the ultrasonic sensor (2) on a horizontal plane parallel to the emitting surface (22) and a second straight line perpendicular to the first straight line, and connect the emitting surface (22) of the ultrasonic sensor (2) to the attachment member (1).
