Abstract

See full text

A resonator that includes a piezoelectric vibrating portion; a retainer provided in at least part of an area surrounding the piezoelectric vibrating portion; a first node generating portion disposed between the piezoelectric vibrating portion and the retainer; a first connecting arm that connects the first node generating portion to a region in the piezoelectric vibrating portion that faces the first node generating portion; and a first retaining arm that connects the first node generating portion to a region in the retainer that faces the first node generating portion. The first node generating portion is substantially symmetrical with respect to each of two lines passing through a center of the first node generating portion along a first direction and a second direction orthogonal to the first direction, with the first direction being a direction that the first connecting arm connects the first node generating portion to the piezoelectric vibrating portion.
