RFID TAG AND METHOD OF MANUFACTURING RFID TAG
First Claim
1. An RFID tag comprising:
- a tag main body having a communication antenna, a circuit chip electrically connected to the antenna to perform wireless communication via the antenna, and a tabular sealing member in which the antenna and the circuit chip are enclosed;
a print layer formed on a first surface of the tag main body by printing; and
a protective film that covers the print layer;
wherein the print layer is formed only in a central area of the first surface surrounded by a marginal area of the first surface extending along the outer edge of the first surface, andthe protective film includes a covering portion that coversthe print layer and an adhering portion that lies off the print layer while surrounding the outer edge of the print layer and adheres to the first surface.

5. A method of manufacturing a RFID tag, the method comprising the steps of:
-
preparing; (a) an inlay having a base, a communication antenna arranged on the base, and a circuit chip connected to the antenna to perform wireless communication via the antenna, (b) a first sealing member disposed on a first face of the inlay, (c) a second sealing member disposed on a second face of the inlay, the second sealing member having a first surface which is opposite to a surface where the inlay is disposed and on which a print layer is formed by printing in only a central area of the first surface, the central area being surrounded by a marginal area of the first surface extending along the outer edge of the first surface, and (d) a protective member that covers the print layer and has an area spreading beyond the print layer; stacking the first sealing member, the inlay, the second sealing member, and the protective member in this order; and heating and pressurizing the entire stack of the first sealing member, the inlay, the second sealing member, and the protective member, so that the inlay is enclosed by the first sealing member and the second sealing member and there is formed a protective film having a covering portion that covers the print layer and an adhering portion that lies off the print layer while surrounding the outer edge of the print layer and adheres to the first surface. - View Dependent Claims (6)
