Claims

[Claims for Utility Model Registration] The piezoelectric substrate has an element that performs energy trapping type vibration in response to an electric signal applied to a vibrating electrode formed on the piezoelectric substrate, and the element is provided on the piezoelectric substrate. The piezoelectric substrate is electrically conductively bonded with a conductive adhesive to a metal terminal integrally molded with the resin case at the lead-out electrode part, and the vibrating part of the piezoelectric substrate is supported so as to be able to vibrate within the resin case. In the component, the metal terminal has a conductive adhesive part with the extraction electrode part that is partially exposed in the resin case, and this conductive adhesive part is a first adhesive part facing the extraction electrode part of the piezoelectric substrate. A structure of a piezoelectric component characterized in that it has a second adhesive part that is bent at a substantially right angle from the first adhesive part.
