In a ceramic resonator of the type comprising an outer casing, a disc shaped ceramic resonator element, a pair of resilient terminal members on both sides of the resonator element, each including a projection for supporting the resonator element, and a split inner casing contained in the outer casing for containing the resonance element and terminal members, one half of the split inner casing is provided with an annular rib on its mating surface and a cylindrical recess inside the annular rib, and the other half of the split inner casing is provided with a cylindrical recess on its mating surface for receiving the annular rib whereby when the resonator and the terminal members are assembled in a space defined by the recesses of the inner casing halves, the resonator element is resiliently supported between the projections of the terminal members at its geometrical center.
