An antenna element includes a feeding path unit connected to a feeding point, first and second antenna main body units, and first and second short-circuit path units. The first antenna main body unit has one end connected to the feeding path unit and the other end that is opened. The second antenna main body unit has one end connected to a connection point between the feeding path unit and the first antenna main body unit and the other end that is opened. The first short-circuit path unit contributes to a resonance to a radio signal in a predetermined first frequency band, and is formed between the connection point and a ground point. The second short-circuit path unit contributes to a resonance to a radio signal in a second frequency band higher than the first frequency band, and has a path length different from that of the first short-circuit path unit.
