[Problem] To provide an antenna that can be used over a broad bandwidth. [Solution] An antenna (10A) is provided with: a dielectric substrate (11); an unbalanced power supply member (12) having a parasitic part (23) and a power supply part (24); a resonance conductor (13) having a connection area (26), a first resonance area (27), and a second resonance area (28); a ground conductor (14) having a first ground area (32) and a second ground area (33); and a radiation conductor (15) having a first radiation area (37) and a second radiation area (38). On the antenna (10A), first through third radiation stepped portions (42a-42c) are formed in a first rear end part (41) of the second radiation area (38), and first through third radiation stepped portions (44a-44c) are formed on a second rear end part (43) of the second radiation area (38). |
