Abstract:
1. A piezo-electric oscillator comprising: resin; a substrate having an upper face, a bottom face, a conduction terminal portion, and a mounting terminal portion at the bottom face, at least the conduction terminal portion being sealed with the resin; a piezo-electric vibrator including a package a cover plate, a piezo-electric vibration piece, and an external terminal portion, the piezo-electric vibration piece being housed within the package, the package being fixed to the upper face of the substrate and sealed with the cover plate, the external terminal portion at a surface of the package being electrically coupled with the piezo-electric vibration piece; and an oscillation circuit element having an oscillation circuit, the oscillation circuit element being fixed to a face of the package opposite to the substrate, the conduction terminal portion on the upper face of the substrate being electrically coupled with the mounting terminal portion, and the external terminal portion and the conduction terminal portion being electrically coupled with the oscillation circuit element.
