Abstract

An ultrasonic sensor includes a magnetic substance, a diaphragm, and an electromagnetic transducer. The electromagnetic transducer is disposed opposing the magnetic substance across an outer plate of a vehicle. The diaphragm has the shape of a thin film with a film thickness direction along an axial direction parallel to a directional axis. The diaphragm is able to ultrasonically oscillate by being joined to an outer surface of the outer plate at an outer edge in a radial direction crossing the directional axis. With the outer edge of the diaphragm joined to the outer surface of the outer plate, an internal space that expands and contracts along the axial direction in response to ultrasonic oscillation of the diaphragm is formed between the diaphragm and the outer surface of the outer plate.
