PROBLEM TO BE SOLVED: To provide a small dielectric resonator antenna having a wide band. SOLUTION: A first dielectric plate 2 having a disk-like hole 20 is provided on a grounding plate 1 having a hole 10, and a columnar dielectric resonator 3 having a columnar cavity 30 is provided thereon. The external surface and internal surface (side surfaces of the cavity 30) of the dielectric resonator 3 are the same in center axis. Since the hole 20 of the first dielectric plate 2 and the cavity 30 of the dielectric resonator 3 are the same in dimension of the bottom surface and one columnar space is formed by these, a conductor mass 4 is filled in the space. Also, a feeding probe 6 consisting of a linear or narrow strip-like conductor is provided parallel to the center axis on the external side surface of the dielectric resonator 3, and a center conductor 51 of a coaxial cable 5 is connected thereto.
