Abstract
A surface mount quartz crystal oscillator comprises a package body having a recess, a quartz crystal blank having extending electrodes extending from the outer periphery of the crystal blank, an IC (integrated circuit) chip secured to an inner bottom surface of the recess and having at least an oscillator circuit connected to the crystal blank, and an insulator disposed on the IC chip. A pair of conduction terminals are disposed on an inner wall surface of the recess and electrically connected to the IC chip. The crystal blank is secured to the insulator with a conductive adhesive at positions from which the extending electrodes are extended, and the conductive adhesive electrically connects each extending electrode to one conduction terminal associated therewith.
