An antenna 10 includes a base print layer 2 printed in a predetermined antenna pattern on a surface of a workpiece 1, and an electroless plating layer 3 disposed on the surface of the base print layer 2. The base print layer 2 is formed of an ink 2a and metal particles 2b. The ink 2a has been printed with a substantially uniform thickness to form an ink layer, in which some of particles of the metal particles 2b are buried. The metal particles having a large diameter are partially protrudent from the ink layer, and part of the ink 2a covering the protrudent portions have been removed. |
