Abstract
An ultrasonic sensor includes an inner case mainly made of plastic and having a shape of a cylinder with a bottom portion. A conductive film is attached to the bottom portion. An electrode formed at a surface of the piezoelectric vibrator is attached to the conductive film to be electrically connected with the conductive film. Therefore, by connecting leads with the conductive film and another electrode at the other side of the piezoelectric vibrator, the electric conduction between an external circuit and both electrodes at both surfaces of the piezoelectric vibrator is ensured.
