PROBLEM TO BE SOLVED: To provide a support platform integrated type dielectric resonator in which no jointing material oozes to the peripheral surface of a through hole and the jointing reliability of the dielectric resonator and a support platform is high. SOLUTION: The support platform integrated type dielectric resonator comprises a cylindrical dielectric resonator 11 (that is made of titanate such as MgTiO<SB>3</SB>or the like) and a cylindrical support platform 12 (that is made of alumina or the like) that are connected to each other at one-end faces. In joint faces of the dielectric resonator 11 and the support platform 12, an edge of the opening surface of the through hole of the dielectric resonator is positioned more inward from an edge of the opening surface of the through hole of the support platform over the entire circumference thereof. Besides, the support platform has a cutout 121 in at least part of the edge of the opening surface of its through hole, while the cutout is filled with a jointing material (that is an inorganic jointing material such as a glass grace based jointing material or the like, an organic jointing material such as an epoxy-based jointing material or the like).
