Abstract
Ultrasonic sensor () includes piezoelectric element (), first acoustic matching layer (), and second acoustic matching layer () which are laminated and bonded together, piezoelectric element () having a rectangular bonding surface. First acoustic matching layer (), which is adjacent to piezoelectric element (), is bonded to piezoelectric element () using thermoplastic resin injected from a thickness direction of first acoustic matching layer () in a manner that a flow direction of the thermoplastic resin matches a longitudinal direction of piezoelectric element (). With this configuration, ultrasonic sensor () that exhibits excellent temperature characteristics against such as thermal shock is provided.
