PROBLEM TO BE SOLVED: To provide a method for effectively and successfully forming an inductive element used in a resonant circuit device or another non-contact recognition type device. SOLUTION: (a) A conductive metal sheet that can be patterned is brought into close contact with a surface of a self-support substrate, and is patterned so that a gap is formed between conductive metal segments, and finally an induction coil is formed. Forming a series of individually separated segments made of conductive metal on the substrate surface, (b) removing excess metal present in the gap group formed in (a), (c) A continuous induction coil is formed by printing a conductive ink segment group in the gap group formed in the above (b), and (d) connecting the induction coil to a capacitor or an RFID computer chip, and performing intensive or scattered static electricity. A capacitance is applied to form a resonant circuit device. It is preferable that the conductive metal sheet is adhered to the substrate surface by any one of die stamping, hot stamping, knife embossing, and die embossing. Unnecessary metals are easily removed, and a high-performance device can be manufactured at low cost. |
