Supporting structure for piezoelectric resonator, and electronic device, ladder filter, and communication apparatus

摘要

A piezoelectric device includes a substrate. The substrate is provided with pattern electrodes located on a major surface thereof. Intermediate portions of external electrodes of a piezoelectric resonator are supported by a supporting member at land electrodes provided at ends of the pattern electrodes. The supporting member includes a plurality of substantially cylindrical units made of nickel. A filler made of an epoxy resin is formed around the substantially cylindrical units. <IMAGE>
