Abstract:
1. A dielectric resonator comprising: a metallic casing having an opening; a metallic cover which covers said opening; and a dielectric resonance element having a pair of flat surfaces formed opposite from each other, one of the pair of flat surfaces contacting a bottom portion of said casing, wherein at least one of said cover and said bottom portion has a resilient portion which supports said dielectric resonance element and presses said one of the pair of flat surfaces by a biasing force so as to follow expansion or contraction of said dielectric resonance element due to a change in temperature, and wherein the biasing force applied from said resilient portion is obtained by bent portion of said cover or a bent portion of said bottom portion contacting one of said pair of flat surfaces or an edge portion thereof, said bent portion in contact being bent in a direction away from the one of said pair of flat surfaces or an edge portion thereof.
