Abstract
An ultrasonic sensor is secured to an attachment object and passes through the attachment object. The ultrasonic sensor includes an oscillator which has a transceiving surface which transmits or receives an ultrasonic wave, a cylindrical elastic member which surrounds an outer surface of the oscillator extending from the transceiving surface in a thickness-wise direction of the transceiving surface and has an inner surface contacting the outer surface of the oscillator, a body which has a housing with a bottom and in which the to oscillator and the elastic member are disposed except a protruding portion on a side of said transceiving surface, and an annular body which surrounds the protruding portion of the elastic member and is disposed in the body in contact with a front of the attachment object. A gap is provided between an outer surface of the protruding portion of the elastic member and an inner surface of the annular body which faces the outer surface of the protruding portion, thereby minimizing the ingress of water into the body.
