Abstract
A piezo-electric oscillator has a reduced manufacturing cost using a general purpose piezo-electric vibrator, while coping with miniaturization. The piezo-electric oscillator has resin; a substrate having an upper face, a bottom face, a conductive terminal portion, and a mounting terminal portion at the bottom face; and a piezo-electric vibrator including a package, a conductive portion, a cover plate, a piezo-electric vibration piece, an external terminal portion; and an oscillation circuit element having an oscillation circuit. The piezo-electric vibration piece is housed within the package and, the package is fixed to the upper face of the substrate and sealed with the cover plate. The external terminal portion at a surface of the package is electrically coupled with the piezo-electric vibration piece and, at least the conductive portion excluding the mounting terminal portion is sealed with the resin. The oscillation circuit element is fixed to a face of the package opposite to the substrate. The conduction terminal portion on the upper face of the substrate is electrically coupled with the mounting terminal portion, and the external terminal portion and the conduction terminal…
