PROBLEM TO BE SOLVED: To provide a package for piezoelectric vibrators which accurately vibrates the accommodated piezoelectric vibrator, by preventing a short circuit of wiring lines between a check terminal and an external electric circuit substrate when the package is installed in the substrate. SOLUTION: An accommodation package for piezoelectric vibrators comprises a rectangle insulator 1 that has a concave mounting portion 5 for mounting the piezoelectric vibrator 3 and a semiconductor 4 on the surface, a cut-in portions 6a being cut-in at the side of the insulator 1 from the upper surface to the bottom surface, and a check terminal 9 to check oscillation frequency characteristics of the piezoelectric vibrator 3 by electrically connecting an external frequency characteristic measuring instrument to the vibrator 3 via a wiring conductor 8a formed at a location apart from the bottom of the insulator 1. The package enables the piezoelectric vibrator 3 and the semiconductor 4 to work accurately due to no contact between the check terminal 9 and wiring parts for an external electric circuit substrate.
