PIEZOELECTRIC ELECTRONIC COMPONENT

摘要

A piezoelectric electronic component suitably used in a cellular phone or the like and capable of achieving reductions in size and profile is provided. A piezoelectric element 3 oscillating in response to application of an input signal and outputting an output signal corresponding to the oscillations is provided on a substrate 1. The piezoelectric element 3 includes a pad 3c 1 and the like, the pad 3c 1 inputting and outputting the input and output signals. A shell member 5 serving as a sealing member constituted of an insulation film covering the piezoelectric element 3 is provided on the substrate 1, the shell member 5 being remote from the piezoelectric element 3. The shell member 5 includes a through hole 5a above the pad 3c 1 or the like, and the through hole 5a is occluded with an electrode 17.
