PROBLEM TO BE SOLVED: To provide a wideband dipole antenna easy to miniaturize. SOLUTION: A dipole antenna 1 includes a dipole radiation element 3 having a pair of radiation conductors 7, 8 having feed points P1, P2, and a non-power supplied radiation element 4 excited by the dipole radiation element 3 formed on the surface of a flexible dielectric substrate 2 constituted of a transparent film. The dipole radiation element 3 has an outer shape having the central portion thereof narrower than the both ends in the longitudinal direction. The above narrow portion forms an isosceles triangular-shaped recess 9. Further, a non-power supplied radiation element 4 of a substantially similar figure is penetratingly disposed in the recess 9, so that the overall shape of the both radiation elements 3, 4 is set to be a substantially rectangular shape.
