An antenna comprises a base member ( 3 ), a ground conductor ( 5 ), a first antenna element ( 7 ) and a second antenna element ( 9 ). The base member ( 3 ) is formed in a thin plate shape and made of dielectric material. The ground conductor ( 5 ) is formed of a thin-film shaped and rectangular conductor and disposed on the base member ( 3 ). The first antenna element ( 7 ) is formed of a thin-film shaped and L-shaped conductor, is disposed on the base member ( 3 ) and has one end connected to one end ( 5 A) of the ground conductor ( 5 ). The second antenna element ( 9 ) is formed of a thin-film shaped and rectangular conductor and is disposed on the base member ( 3 ) to be isolated from the ground conductor ( 5 ) and the first antenna element ( 7 ).
