Abstract: An embodiment of an artificial dielectric resonator that can enhance a relative dielectric constant in a basic mode is provided. The artificial dielectric resonator has a first group of a series of metal strips including a plurality of metal strips each in a thin sheet shape arranged with microscopic gaps provided in a longitudinal direction, and a second group of a series of metal strips including a plurality of metal strips each in a thin sheet shape arranged with gaps provided in a longitudinal direction, the first group of a series of metal strips and the second group of a series of metal strips are disposed close to each other in a thickness direction of the metal strips, and the metal strip of one metal strip group is disposed to face oppositely disposed gaps and cross vertically adjacent gaps of the other metal strip group.
