Abstract:
1. A piezoelectric oscillator, comprising: a plurality of leads formed of two lead frames; and terminals formed on said plurality of leads; said terminals being at least connection terminals to connect with a piezoelectric resonator and mounting terminals to mount to a mounting board; said connection terminals formed on one of said lead frames on one side; said mounting terminals formed on the other of said lead frames on said other side; said connection terminals and said mounting terminals distanced one from another being arrayed in multiple tiers in a direction substantially perpendicular to a main plane of the lead frame, at least one connection terminal and at least one mounting terminal overlapping in plan view; said piezoelectric resonator formed by sealing a piezoelectric resonator element within a resonator package being mounted on said connection terminals; an IC forming an oscillating circuit being mounted on said lead frame; and said lead frame and said piezoelectric resonator being sealed within a resin package such that the principal surface of said mounting terminals are exposed outwards, thereby forming a resin package outwards.
