Abstract
A piezoelectric resonant component is constructed such that it is possible to reduce the thickness of an exterior case member while preventing fracture and chipping of the exterior case member. The piezoelectric resonant component preferably includes exterior substrates defining exterior case members and being stacked on an energy trap type piezoelectric resonant element via adhesive layers disposed therebetween so as to define spaces for allowing for free and unhindered vibration of the piezoelectric vibration portion, and a plurality of external electrodes disposed on the surfaces of the exterior substrates on the opposite side of the surfaces thereof fastened to the piezoelectric resonant element are arranged so as not to overlap with the spaces through the intermediary of the exterior substrates.
