<p>PROBLEM TO BE SOLVED: To surely operate a tag, even if an antenna coil is brought into close contact with an article, made of metal, and to form a thickness of the antenna coil to be extremely thin. SOLUTION: The antenna coil 10 comprises an insulation member 11, a series of conductors 12, in which forward routes 12a and return routes 12b are formed alternately in a zigzag manner on the front surface of the insulating member, and a first core member 13 for coating the return routes 12b adhered to a rear surface of the member 11 from the rear surface of the member 11. A second core member 14 may be coated on the forward routes 12a on the front surface of the member 11 and may be adhered, so that its end is superposed with the end of the adjacent first core member 13. A plurality of conductive lines are formed in a zigzag manner on the front surface of the member 11 at a predetermined interval along with each other, and a series of the conductors 12 may be constituted, by connecting the terminating end of the conductor to the starting end of the adjacent conductor.</p> |
