1. A dielectric resonator comprising:
a dielectric member;
an electrode provided on an outer surface of the dielectric member; and
a line pattern having a first end that is short-circuited with respect to the electrode and a second end that is open with respect to the electrode, the line pattern being provided on a portion of the outer surface of the dielectric member,
wherein the line pattern includes an electrode gap that divides the line pattern into a signal input/output portion provided on the second end that is open with respect to the electrode, and a ground portion provided on the first end that is short-circuited with respect to the electrode.
