Abstract

The invention relates to a piezoelectric oscillator wherein a case and a stem are coated with a solder containing 90% and higher of lead, an inner lead is also coated with the solder thereby fixing a piece of piezoelectric oscillator by melting the solder. The invention further relates to a piezoelectric oscillator wherein the piezoelectric oscillator is performed casing by resin or metallic plate, and to a piezoelectric oscillating apparatus wherein IC and a piezoelectric oscillator are internally mold to achieve a molding of high efficiency without inferiority while surface mounting.
