<p><P>PROBLEM TO BE SOLVED: To efficiently manufacture a thin type coil such as an antenna coil, and to easily cope with the manufacturing of a coil different in the number of turns. <P>SOLUTION: The coil 9 is manufactured by sequentially carrying out steps of: forming a thin film 2 formed of a conductive material on one surface of a long-sheet-shaped flexible base 1; manufacturing an original roll of coils 4 by winding the flexible base 1 having the thin film 2 formed of the conductive material in a roll shape; manufacturing a wound body 6 by unwinding the flexible base 1 having the thin film 2 formed of the conductive material from the original roll of coils 4 and rewinding it around an outer periphery of a core 5; cutting out a coil intermediary body 7 by cutting the wound body 6 in a direction orthogonal to the length of the core 5; polishing a cut surface 7a of the coil intermediary body 7 cut out of the wound body 6; and attaching lead wires 8 to both ends of a winding part 7b formed of a conductive material in the coil intermediary body 7. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
