Abstract
A piezoelectric component includes leads and being arranged to suppress the adhesion of solder or a conductive adhesive agent to lead-out electrodes or vibration electrodes thereof, which is therefore resistant to the deterioration of electrical characteristics such as resonance characteristics, and which minimizes fluctuation of the electrical characteristics. In this piezoelectric component having the leads, the vibration electrodes are provided on each of the first and second main surfaces of a piezoelectric plate, and each of the vibrating electrodes is connected to a terminal electrode via a lead-out electrode. Each of the holding portions of a lead terminal is bonded to the terminal electrode, and is arranged so as not to extend onto the lead-out electrode.
