Abstract
An open resonator capable of measuring dielectric characteristic of a sample with high accuracy by removing unnecessary higher-order mode resonance. The open resonator includes: a first spherical reflection mirror having a first reflection spherical surface; and a second spherical reflection mirror having a second reflection spherical surface arranged to face the first reflection spherical surface. At least one of diameters of opening surfaces of the first reflection spherical surface and the second reflection spherical surface exposed to a space between the first reflection spherical surface and the second reflection spherical surface is equal to or less than a half of a distance between the first reflection spherical surface and the second reflection spherical surface.
