PIEZOELECTRIC ELECTRONIC COMPONENT, AND PRODUCTION METHOD THEREFOR, COMMUNICATION EQUIPMENT |
摘要 |
<p>A piezoelectric electronic component suitably used in a portable phone or the like, and able to be downsized and made low in profile. A piezoelectric element (3) vibrated by an applied input signal, for outputting an output signal by the vibration is formed on a substrate (1). The piezoelectric element (3) is provided with a pad unit (3c1) for the above input and output signals. A shell member (5), as a sealing member consisting of an insulation film formed to cover the piezoelectric element (3) in a spaced-apart manner, is formed on the substrate (1). The shell member (5) has a through hole part (5a) above the pad unit (3c1) or the like, and the through hole part (5a) is closed by an electrode unit (17).</p> |
