PIEZO-OSCILLATOR AND MANUFACTURING METHOD THEREOF

摘要

The present invention is intended to provide a piezoelectric oscillator whose size can be reduced and whose production cost can be saved by using a versatile piezoelectric resonator. A piezoelectric oscillator, at least a conductive part except for a mounting terminal portion being sealed with resin, includes: a substrate 60 whose bottom is provided with a mounting terminal portion 62; a piezoelectric resonator 35 housing a piezoelectric resonator element 37 in a package 36 fixed on the upper surface of the substrate and sealed with a lid, and having external terminal portions 42, 43 electrically coupled to the piezoelectric resonator element on the surface of the package; and an oscillator circuit element 50 included in an oscillator circuit and fixed on a side of the package 36 opposite to another side facing the substrate 60. The substrate 60 includes conductive terminal portions 63a through 63d electrically coupled to the mounting terminal portion 62 on its upper surface. The external terminal portions 42, 43 and the conductive terminal portions 63a through 63d are electrically coupled to the oscillator circuit element 50.
