Summary:PROBLEM TO BE SOLVED: To provide a piezoelectric device which enables precise frequency adjustment and is equipped with superior performance of shock resistance, even if it is made compact in size. SOLUTION: This piezoelectric device is equipped with a package 36, which is made to form an inner space S by stacking a plurality of ceramic boards, a piezoelectric oscillation piece 32 which is accommodated in this package, and a glass cover 39 for sealing the package by being fixed to the top of the package via low-fusing point glass, and reinforcing materials 45a and 45b are arranged between at least a part of mutual stacked boards seated above or in between the top of the package and the low-fusing point glass.
