PROBLEM TO BE SOLVED: To provide an antenna device capable of being made into a broad band while maintaining half-value width in a horizontal plane. SOLUTION: The antenna device is provided with a dielectric substrate, a dipole element formed on both surfaces of the dielectric substrate, a feeding line connected through a feeding point of the dipole element, a partially cylindrical parasitic element arranged adjacently to the dipole element, a partially cylindrical reflector arranged at a position opposite from the parasitic element with respect to the dielectric substrate.
