したことを特徴とする圧電磁器共振子。 A gate-shaped piezoelectric ceramic diaphragm with four vibrating parts, two on each side of the diaphragm, is connected and fixed to a printed circuit board or metal electrode plate using solder or conductive adhesive, and then sealed with a case. In a piezoelectric resonator that is coated with a cushioning material and then sealed with an epoxy resin or the like so as not to impede the vibration of the piezoelectric ceramic diaphragm, a plurality of the above-mentioned gate-shaped piezoelectric ceramics having different natural vibration frequencies are used. A piezoelectric ceramic resonator characterized by having diaphragms connected and fixed in parallel.
