PURPOSE: An ultrasonic sensor is provided to facilitate product manufacturing by eliminating the need for a soldering process for the assembly of components placed inside the same and the connection of a lead line. CONSTITUTION: An ultrasonic sensor(100) includes a case(110) with a cylindrical shape, a piezoelectric element(120), a first terminal(151), a second terminal(153), a connecting means(130), and a temperature compensating element(140). The piezoelectric element is placed on the floor surface inside the case. The first terminal and the second terminal are applied with positive and negative voltage from the outside. The connecting means is equipped with a conductive component, which is composed of a first area and a second area connected with the first terminal and the second terminal, respectively, and a supporting component, which is attached to the bottom surface of the conductive component. The temperature compensating element penetrates between the first area and the second area of the conductive component and is inserted into the supporting component.
