Abstract
A surface mount device-type low-profile oscillator is provided. A main surface of an IC chip unit is joined to a bottom surface where the external terminals of a crystal unit section are formed. An integrated circuit portion includes a circuit forming, together with the crystal unit of the crystal unit section, an oscillator circuit on the main surface of the IC chip unit, and IC terminals formed with a plurality of IC electrode terminals, and two connection terminals connecting the external terminals of the crystal unit section are provided. The IC electrode terminals and mounting terminals are electrically connected with electrical columns provided in via holes penetrating in the direction of thickness of a silicon plate of a bare chip. The crystal unit section and the IC chip unit are joined with an anisotropic conductive adhesive applied to the main surface of the IC chip unit.
