PURPOSE:To execute a fine adjustment by the constitution which is low in its cost and compact, by constituting the titled mechanism so that a plate member consisting of a metal or a dielectric is placed in the opening part of a coupling hole, and this plate member covers a part or the whole of the opening part of the coupling hole. CONSTITUTION:In an integral molding dielectric resonator, the resonator body 1 is formed in a shape of a rectangular parallelopiped, and a through-hole 2 and a coupling hole 3 are provided on the inside. As for the through-hole 2, its cross section is formed circularly, and plural pieces are placed at a prescribed interval, and constituted so that input and output terminals can be inserted. As for the coupling hole 3, its cross section is formed rectangularly, and said hole is placed between the adjacent through- holes 2. Also, each through-hole 2 and the coupling hole 3 extend in parallel to each other, and opened to a short surface 4 of the resonator body 1, respectively. To this short surface 4, a metallic case 5 is fixed. In the metallic case 5, a cut-raised piece 6 is formed in the part corresponding to the coupling hole 3, and this cut-raised piece 6 is formed in a rectangular shape corresponding to the coupling hole 3, and its tip part is inserted into the coupling hole 3.
