The present invention provides a method of fabricating a crystal oscillator with pedestal for surface mounting, which is provided on a base surface of a crystal oscillator from which a pair of lead wires extends and which is formed by injection molding using a mold with a liquid-crystal polymer as raw material; wherein protrusions that follow the shape of said mold are provided on at least a corner around the outer periphery of the surface of the oscillator pedestal facing said base surface of said crystal oscillator; a non-defective product is assumed to be one in which the upper surface of each of said protrusions is a flat surface, but a defective product is assumed to be one in which the flat surface of said protrusion is ridged; and only a non-defective product is mounted onto the base surface of the crystal oscillator. This makes it possible to provide a method of fabricating a crystal oscillator by which reliability is increased while the strength of the oscillator pedestal is maintained.
