Abstract
Abstract A thin antenna 20 having a satisfactory length, its making method, and an electronic device such as a wristwatch having such antenna. The antenna 20 is formed on a lower surface of a transparent plate 5 by printing an ornamental layer 22 on a lower surface of the transparent plate 5, forming a conductive ink layer 23 on the ornamental layer 22, and further forming plated metal layers 24, 25 on the conductive ink layer 23. Since the antenna 20 is thin as a whole, it may be provided within a small electronic device such as a wristwatch.
