ULTRASONIC SENSOR AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed herein are an ultrasonic sensor and a method of manufacturing the same. The ultrasonic sensor includes: a conductive case; a piezoelectric element fixed to a bottom. surface of the case through a conductive adhesive; a temperature compensation capacitor positioned over the piezoelectric element; a first lead wire lead from the outside of the case and electrically connected to one surface of the temperature compensation capacitor and the piezoelectric element; a second lead wire lead from the outside of the case and electrically connected to the other surface of the temperature compensation capacitor and the case; and a first molding part closely adhered to outer portions of the temperature compensation capacitor and the first and second lead wires.
