[Problem to be Solved] To provide an antenna which can be used in a wide band. [Solution] An antennaA includes a dielectric substrate, an unbalanced power supply memberhaving a non-power supply unitand a power supply unit, a resonance conductorhaving a connection area, a first resonance areaand a second resonance area, a grounding conductorhaving a first ground areaand a second ground area, and a radiation conductorhaving a first radiation areaand a second radiation area. At the antennaA, first to third radiation stepped portionstoare formed at a first rear end portionof the second radiation area, and first to third radiation stepped portionstoare formed at a second rear end portionof the second radiation area
