MANUFACTURING METHOD OF SHEET ANTENNA COIL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a sheet antenna coil at a low cost with a simple configuration and a high efficiency. SOLUTION: A rod material 13 formed by winding a layer of a sheet 11 and a bar 12 onto a side face of a rod core member 10 for a plurality of number of times is sliced in a lateral cross-sectional direction to obtain a sheet antenna coil 14 without the need for a nozzle, conductive paint and an agent different from a conventional manufacturing method by a simple configuration above. Even in the case of the sheet antenna coil 14 requiring many numbers of turns, it can be coped with by increasing number of windings of the sheet member 11 and the bar 12.
