<p>PROBLEM TO BE SOLVED: To provide a sheet type antenna coil with an IC connection terminal which can have an IC chip connected directly to a terminal of the antenna. SOLUTION: A nonconductive core material 1 having a storage groove 2 along the length, a beltlike conductor 3 having at both ends a folding/coiling start edge 3A and a coiling end 3B as connection terminals, and a sheet 4 of a nonconductor with good flexibility are prepared; and the folding/coiling start edge 3A of the beltlike conductor 3 is stored in the storage groove of the nonconductive core material 1, and the overlapped conductor 3 and sheet 4 are wound around the core material 1 to form a coiling body. The core material 1, conductor 3, and sheet 4 are adhered together in one body to form an antenna raw material 5, which is sliced thin in the crossing direction to form sheet type antenna coils 6 having specific spiral coils.</p> |
