PURPOSE: A structure of a piezoelectric resonator case is provided to improve reliability of a piezoelectric resonator case by changing an internal structure of the piezoelectric resonator case. CONSTITUTION: A housing(10) has a box shape and includes an opened front portion. A couple of support members(20,60) are formed with a couple of flat plates. The support members(20,60) have portions curved to an upper direction and a lower direction, respectively. Insertion grooves(22,62) are formed in the curved portions of the support members(20,60). Projective sheets(31,51) are formed on each center portion of a couple of vibration plates(30,50), respectively. Connection sections(32,52) are projected to the front direction of the vibration plates(30,50). The vibration plates(30,50) are formed with cone shapes, respectively. A disc(40) is located between the vibration plates(30,50).
