The present invention relates to an ultrasonic wave sensor for a vehicle, including: a pillar-shaped guard having each opening at both ends in the longitudinal direction; a matching layer formed on the opening side of one end of the guard, and including an adhesive and a filler; a piezoelectric element disposed on the matching layer at the inner space side of the guard; and a support layer disposed in the inner space of the guard from the opening at the other end of the guard to the matching layer and the piezoelectric element. The present invention does not contain a substance which causes a decrease in sensitivity of transmission and reception, thereby the sensor having excellent performance.
