Abstract
An energy-trap chip-type piezoelectric resonance component has a resonance part defined by first and second resonance electrodes which are formed on a pair of opposite surfaces of a piezoelectric plate so that vibrational energy of the resonance part is partially trapped, and first and second holding plates which are bonded to both sides of the pair of opposite surfaces through adhesive layers, and the adhesive layers are applied onto regions other than that provided with the resonance part for allowing vibration of the resonance part, while the same contain granular solids.
