Patent ID: 7123107

Claim:
A piezoelectric oscillator including a layered lead frame, comprising: two lead frames; connection leads to connect with a piezoelectric resonator being formed on one of said lead frames on one side and said connection leads have an inclined portion, the inclined portion of the connection leads being erected to one said side so as to form connection terminals; mounting leads to mount to a mounting board are formed on the other of said lead frames on said other side and said mounting leads have an inclined portion, the inclined portion of the mounting leads being erected to the other side so as to form mounting terminals; and an IC forming an oscillating circuit being mounted on said layered lead frame, said piezoelectric resonator formed by sealing a piezoelectric resonator element within a resonator package being mounted on said layered lead frame; and said layered lead frame and said piezoelectric resonator being sealed within a resin package such that the inclined portions of the connection lead and the inclined portion of the mounting lead are sealed internally and that the principal surface of said mounting terminals are exposed outwards, thereby yielding a completed article.
