Patent ID: 7795982

Claim:
A surface-mount type crystal oscillator comprising: a container body with a recess; a first holding terminal and a second holding terminal provided in the recess; a crystal blank accommodated in the recess and including an excitation electrode on each principal surface of the crystal blank, the crystal blank being secured to the first and second holding terminals so that the paired excitation electrodes are electrically connected to the first and second holding terminals, respectively; and an IC chip accommodated in the recess and on which an oscillating amplification element for an oscillation circuit using the crystal blank is at least integrated, the IC chip including a first terminal and a second terminal on respective opposite sides of one end of the IC chip, the first and second terminals being used to electrically connect the amplification element to the crystal blank, wherein a first circuit terminal and a second circuit terminal are provided in the recess in proximity to the first connection terminal, the first circuit terminal being electrically connected to the first holding terminal, the second circuit terminal being electrically connected to the second holding terminal, wherein a third circuit terminal and a fourth circuit terminal are provided in the recess in proximity to the second connection terminal, the third circuit terminal being electrically connected to the first holding terminal, the fourth circuit terminal being electrically connected to the second holding terminal, wherein the first connection terminal is connected to one of the first and second circuit terminals by wire bonding, and wherein the second connection terminal is connected to one of the third and fourth circuit terminals by wire bonding.
