Abstract:
1. A crystal oscillator comprising: a package body having a recess formed by an inner side wall surface and an inner bottom surface surrounded by the inner side walls; a crystal blank having extending electrodes extending from an outer periphery of said crystal blank; an IC chip secured to the inner bottom surface of said recess and having at least an oscillator circuit connected to said crystal blank; an insulator bonded onto an upper surface of said IC chip; and conduction terminals disposed on the inner side wall surface of said recess and electrically connected to said IC chip, wherein both said crystal blank and said IC chip are accommodated in said recess, wherein said crystal blank is secured to said insulator with a conductive adhesive at positions from which extending electrodes are extended, and said conductive adhesive electrically connects each of said extending electrodes with each of said conduction terminals.
