PROBLEM TO BE SOLVED: To provide an easily manufacturable crystal oscillator support structure. SOLUTION: The crystal oscillator is composed of at least a tuning fork type crystal piece having lengthwise fork branches or a rectangular crystal piece, a package having a recess for housing the crystal piece, and a lid for tightly closing the recess. The package has a pedestal for fixing only lengthwise one end of the crystal piece in the recess. The crystal piece has a broad shoulder at a portion to be fixed to the pedestal and a boss on the lengthwise end. The shoulder and the boss on the crystal piece end serve for positioning and fixing the piece on the pedestal in the package recess. COPYRIGHT: (C)2004,JPO
