Piezoelectric electronic component, and production method therefor, and communication equipment

Abstract

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