ABSTRACT:
A piezoelectric resonance component is constructed to allow for easy automatic assembly and eliminates a short-circuit between a ring terminal and a dot terminal while achieving excellent performance characteristics at a low material cost. In the piezoelectric resonance component, the piezoelectric resonator is contained in an outer case with a ring-shaped peripheral electrode and a dot-shaped center electrode in contact with one side of a sheet-shaped anisotropic conductor. A plurality of protrusions provided on arm portions of the ring terminal and a protrusion on the dot terminal are in pressure-contact with the other side of the anisotropic conductor. A dimension L1 of the anisotropic conductor in the direction in which the arm portions of the ring terminal are led out is shorter than a distance D1 from the edge of a lead portion of the ring terminal to the end of the arm portions, and the anisotropic conductor is biased toward an inner wall of the outer case.
