PROBLEM TO BE SOLVED: To provide an antenna feeder capable of supplying electric power to a dipole antenna by capacitive coupling, even if the distance to the dipole antenna is comparatively long. SOLUTION: The feeder 2 is arranged on a surface 10a of a resin forming article 10 and includes power supply parts 16 and 17 of a dipole antenna 1, associating electrodes 21 and 22, respectively, and stubs 23 and 24. The stub 23 extends from the electrode 21 along a line segment 11a of the contour line possessed by a radiating element 11 so as to substantially touch with a projected image of the radiating element 11, when the dipole antenna 1 is projected on the surface 10a of the resin forming article 10. The stub 24 extends from the electrode 22 along a line segment 12a of the contour line possessed by a radiating element 12 so as to substantially touch with a projected image of the radiating element 12, when the dipole antenna 1 is projected on the surface 10a of the resin forming article 10.
