Abstract:
1. A coaxial resonator, comprising: a first outer conductor connected to a reference potential; a dielectric block which is a dielectric body having a rectangular parallelepiped shape, the dielectric block being provided with a through hole formed so as to pass therethrough from a first side surface to a second side surface opposed to the first side surface of the dielectric block, and being so disposed that a first main surface of the dielectric block abuts on the first outer conductor; an inner conductor disposed in an inside of the through hole; and a second outer conductor with a rectangular box shape having one face which is opened toward the first outer conductor, the second outer conductor having an inside dimension such that the dielectric block is housed therein so as to be spaced from a second main surface of the dielectric block, a third side surface of the dielectric block, and a fourth side surface of the dielectric block, and being connected to the reference potential, wherein the second main surface, the third side surface, and the fourth side surface are conductor-free surfaces.
