PROBLEM TO BE SOLVED: To provide a package for containing a piezoelectric vibrator and a piezoelectric device exhibiting excellent frequency characteristics and long term reliability of operation in which the not fixed end of the piezoelectric vibrator does not touch the bottom face of a recess to impede vibration of the piezoelectric vibrator even if the interval between the piezoelectric vibrator and the bottom face of the recess or a lid becomes extremely small due to reduction in size and thickness of the piezoelectric device. SOLUTION: The package for containing a piezoelectric vibrator comprises an insulating substrate 1 having a recess 3 for containing a piezoelectric vibrator 4 on the upper surface, a protrusion 7 formed at the outer circumferential part on the bottom face of the recess 3 and being fixed with the lower surface of the piezoelectric vibrator 4, and a lid 9 being fixed, at the outer circumferential part of the lower surface thereof, to the circumference of the recess 3 in the upper surface of the insulating substrate 1 wherein the insulating substrate 1 is protruding upward such that the central part of the bottom face of the recess 3 becomes higher than the outer circumferential part thereof.
