Title:
PIEZOELECTRIC COMPONENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2006/118192
Kind Code:
A1
Abstract:
Disclosed is a piezoelectric component (1) comprising a piezoelectric transducer (10) wherein a pair of electrodes (20a, 20b) are formed on both major surfaces of a piezoelectric substrate (11), a pair of frame members (30a, 30b) fitted to both major surfaces of the piezoelectric transducer (10), a pair of sealing substrates (40a, 40b) composed of a light-transmitting resin material and so fitted as to cover the frame members (30a, 30b), opaque coating layers (50a, 50b) respectively formed on the sealing substrates (40a, 40b), and a pair of input/output terminal electrodes (61a, 61b) respectively connected to the electrodes (20a, 20b). By having such a constitution, the state of sealed space and sealing widths of the frame members (30a, 30b) can be checked by visual examination such as direct visual observation or image recognition, and thus a highly reliable piezoelectric component (1) can be obtained. In addition, a mark can be made on the coating layers (50a, 50b).
