PIEZOELECTRIC VIBRATION COMPONENT AND APPLICATION METHOD

摘要

A piezoelectric vibration component (40) is provided with a piezoelectric vibrator (20), a substrate (10), and an electroconductive adhesive (12) for bonding the piezoelectric vibrator (20) to the substrate (10). The electroconductive adhesive (12) contains a silicone-based base resin (121), a crosslinking agent (121), an electroconductive filler (122), and an insulating filler (123). The weight average molecular weight of the silicone-based base resin (121) is 20000 to 102000. The number average molecular weight of the crosslinking agent (121) is 1950 to 4620. The grain diameter of the electroconductive filler (122) and the insulating filler (123) is 10 μm or less.
