1. A resonator comprising:
a conductor formed on a surface of an annular shaped structure, and having a first end and a second end opposite to the first end; and
a capacitor having a first end and a second end opposite to the first end,
wherein a radius of curvature of a first curved side facing a center portion of the annular shaped structure in a cross section of the annular shaped structure is smaller than a radius of curvature of a second curved side facing an outer periphery of the annular shaped structure in the cross section of the annular shaped structure, and
wherein the first end and the second end of the conductor are electrically connected to the first end and the second end of the capacitor, respectively.
