PROBLEM TO BE SOLVED: To provide a package for containing a piezoelectric oscillator in which the piezoelectric oscillator can be secured accurately to a piezoelectric oscillator supporting table by means of an automatic machine employing an image recognizer and can be operated in normal state at all times. SOLUTION: The piezoelectric oscillator supporting table 5, being bonded with the electrode of a piezoelectric oscillator 3, comprises an underlying metallized at; layer 7, an insulating layer 8 having a central through hole 8a formed on the underlying metallize layer 7, and an overlying metallize layer 9 formed on the insulating layer 8 while being connected electrically with the underlayer metallized layer 7 via the through-hole 8a and exposing the outer circumferential part of the insulation layer 8, wherein the layers 7, 8 and 9 are entirely formed by thick film method.
