PROBLEM TO BE SOLVED: To provide a surface mounting piezoelectric oscillator in which imbalance of transversal weight occurring conventionally when a piezoelectric oscillating element and an IC component are mounted, respectively, in upper and lower recesses of an insulating container having an H-type longitudinal cross-section due to cantilever supporting of a piezoelectric oscillating element on an inner pad in the upper surface side recess using conductive adhesive is eliminated while ensuring the installation space of an adjusting terminal in the lower surface side recess, and to provide its package. SOLUTION: The package for a surface mounting piezoelectric oscillator comprises an insulating container 1 of substantially H-type longitudinal cross-section having recesses 2 and 3 in the upper and lower surfaces, two upper surface side inner pads 11 provided closely to one edge in the upper surface side recess in order to cantilever supporting one edge of a piezoelectric oscillating element 12, and a lower surface side inner pad 6 arranged on the ceiling surface of the lower surface side recess in order to mount an IC component 20 wherein the position for forming the lower surface side inner pad in the lower surface side recess is shifted closer to the other end on the side opposite to the upper surface side inner pad than the central position C1 of the insulating container thus stabilizing weight balance between the conductive adhesive and the IC component.
