In addition, in order to protect the IC chip 4 from external force or chemical solution at the time of cleaning, the peripheral surface of the IC chip 4 or the entire surface including the periphery thereof is molded with rubber or resin on the antenna unit 3 on which the IC chip 4 is mounted. Mold with material 5. Alternatively, as shown in FIG. 5B, an antenna unit 3 made of a metal wire is provided, and the IC chip 4 is connected to the antenna unit 3 by soldering or the like. Then, molding is performed with a molding material 5 such as rubber or resin.

  As a method of attaching the IC tag 1 to the linen product 11, as shown in FIG. 6A, the attachment fabric 12 is applied so as to cover the IC tag 1, and the attachment fabric 12 is sewn to the linen product 11. Or, as shown in FIG. 6 (b), the end of the linen product 11 is folded back to form a bag-like portion 13, and the IC tag 1 is put therein and the opening 13a of the bag-like portion 13 is sewn. Thus, the IC tag 1 is attached to the linen product 11.

  However, according to these methods, the IC tag 1 is hidden under the attachment fabric 12 or in the bag-like portion 13, and the operator cannot perform the sewing work while looking at the IC tag 1. Therefore, the work must be performed while paying enough attention so that the sewing needle does not hit the IC tag 1, and thus there is a disadvantage that the work efficiency is not good. Furthermore, since the position of the IC tag 1 is not fixed, there is a possibility that the IC tag 1 may be accidentally sewn even when the sewing operation is performed with care. The sewing needle may penetrate and the antenna part 3 may be damaged, and the hole of the sewing needle that has been accidentally opened in the rubber or resin forming the mold material or the film such as polyimide forming the FPC is cleaned. There is a possibility that the IC tag 1 is detached from the linen product due to the external force of the time, or the chemical solution enters the antenna portion 3 through the sewing thread.

  For this purpose, the attachment fabric 12 is sewn to the linen product 11 or the opening 13a of the bag-like portion 13 is sewn at a position away from the outer edge of the IC tag 1. In such a case, the IC tag 1 can easily move under the attachment fabric 12 or in the bag-like portion 13 after sewing, so that there is a problem of promoting bending of the IC tag 1.

  Further, when the attachment fabric 12 is used as shown in FIG. 6 (a), the end 12a of the attachment fabric 12 remains exposed, so that there is a problem that it is gradually unraveled.
