Abstract
A method for manufacturing piezoelectric resonator devices according to the present invention includes the following steps: a wafer forming step of preparing a thick-walled waferintegrally formed with multiple lower lid members; a bonding step of bonding crystal resonator platesto one main surfaceof the wafervia a bonding materialand bonding upper lid memberson the crystal resonator plates via a bonding material; a thinning step of thinning the waferfrom the other main surfaceof the wafer; an external terminal forming step of forming external terminals on the other main surface of the thinned wafer; and a dividing step of cutting the wafer between each adjacent pair of crystal resonators so that multiple crystal resonators are obtained.
