  • Method of producing piezoelectric component
    Patent number: 6192562
    Abstract: A piezoelectric component prevents development of a short circuit between separate electrodes of a piezoelectric element and provides a high level of connection reliability. The piezoelectric component includes a piezoelectric element utilizing a longitudinal oscillation mode and being mounted on a mounting substrate. The piezoelectric element has on one main surface thereof a first electrode and a second electrode formed by dividing electrode material via longitudinally extending linear grooves and, on the other main surface, a third electrode. Conductive support members are secured to node sections of the first and second electrodes so as to be spaced apart from each other with respect to the longitudinal dimension of the piezoelectric substrate. The support members are adhered to and secured to pattern electrodes of the mounting substrate by conductive adhesive.
    Type: Grant
    Filed: September 3, 1999
    Date of Patent: February 27, 2001
    Assignee: Murata Manufacturing Co., Ltd.
