Title:
METHOD OF MANUFACTURING COIL OF IC CARD
Document Type and Number:
Japanese Patent JP2002183696
Kind Code:
A
Abstract:
To prevent an antenna coil of an IC card from becoming a disconnection state and a short-circuit state in manufacturing process.
A first coil 7 is formed on a circuit sheet 1 by screen printing. While, a second coil 10 is formed on a printed wiring board 9 by a printed wiring means. An adhesive is applied on the first coil 7, and the printed wiring board 9 is adhered in layers to the first coil 7. At this time, a conductive adhesive is applied to a central part 7a of the first coil 7 and a tip part 8a of one conductive passage 8 of a pair of conductive passages 8, and both end parts of the second coil 10 are connected to the first coil 7 and the conductive passage 8, simultaneously as with adhesion of the printed wiring board 9.
