ABSTRACT:
A piezoelectric component includes a substrate on which pattern electrodes are disposed. A piezoelectric resonator is placed on the substrate. The piezoelectric resonator generates a longitudinal vibration and includes a base member. External electrodes are disposed at both sides of a groove formed on one side surface of the base member. At the center of the base member in the longitudinal direction, support members made from an electrically conductive material are provided on the external electrodes. The support members are bonded to the pattern electrodes of the substrate via electrically conductive adhesive. An insulating adhesive is disposed between the support members. As a result of this structure, the piezoelectric component has a sufficient bonding strength between the base member and the piezoelectric resonator and prevents a short circuit from occurring between the support members formed in the piezoelectric resonator.
