Abstract
A composite type piezoelectric component has electrodes formed on both major surfaces of a piezoelectric device. These electrodes are electrically connected and mechanically attached to two terminals having top ends shaped so as to receive and support both ends of the piezoelectric device. A capacitor is constructed with a pair of divided electrodes formed on one major surface of a dielectric substrate and another such pair on the other major surface thereof. The capacitor is attached to the two terminals by joining the divided electrodes on one of the major surfaces of the capacitor to the top ends of the terminals so as to leave a clearance between the capacitor and the piezoelectric device. A third terminal is connected to both of the other pair of divided electrodes. These two pairs of electrodes are substantially equally shaped such that directionality is not critical when the capacitor is attached to the terminals.
