Abstract:
A resonator comprising:a piezoelectric element;a lead terminal comprised of an electro-conductive wire material formed by press working with a tapered V shaped or trapezoidal receiving groove for holding an end of the piezoelectric element, the cross-sectional shape of the wire material constituting the lead terminal being substantially circular at the portion not formned with the tapered V shaped or trapezoidal receiving groove and the tapered V shaped or trapezoidal receiving groove having an open portion, with a cross section wider than the thickness of the end of the piezoelectric element, and a pair of inclined straight line side walls extending from a top of the groove to a bottom of the groove; anda capacitor connected to the outer circumference of the top end of the lead terminal in a state with the end of the piezoelectric element held in the receiving groove of the lead terminal so as to constitute a resonance circuit together with the piezoelectric element.
