1. An antenna comprising:
- a base print layer printed in a predetermined antenna pattern on a workpiece, the base print layer being formed of an ink containing a plurality of metal particles having a predetermined particle diameter distribution; and
an electroless plating layer disposed on a surface of the base print layer, wherein,some of particles of the metal particles are buried in an ink layer forming the base print layer, some of the particles of the metal particles are protrudent from the ink layer forming the base print layer, and part of the ink covering the protrudent portions have been removed.

Abstract
This antenna (10) has an underlying print layer (2) which is upon the surface of a material (1) to be printed in a predetermined antenna pattern, and an electro-less plating layer (3) applied to the surface of the underlying print layer (2). The underlying print layer (2) is formed from an ink (2a) and a metallic powder (2b). A portion of the particles of the metallic powder (2b) are entrained within the ink layer in which the ink (2a) has been printed in a substantially uniform thickness. Some particles which are of large particle size project from the ink layer, and a portion of the ink (2a) covering the projecting portions is removed.

7. An antenna manufacturing method comprising:
-
a printing step of forming a base print layer in a predetermined antenna pattern on a workpiece with an ink containing a plurality of metal particles having a predetermined particle diameter distribution; an ink removing step of removing, from those of the metal particles being protrudent from an ink layer forming the base print layer, part of the ink covering the portions protrudent from the ink layer; and an electroless plating step of forming an electroless plating layer on a surface of the base print layer.
