Provided is an IC tag favorably applicable even to linen products. An IC tagusing a magnetic field type tag unitin which an IC chip and a coil antenna to be electrically connected to the IC chip are embedded inside a hard resin material. The IC tag includes: a flexible film made of resin (a base film, a cover film, and a protective film); and an auxiliary antennaformed on the film, wherein the magnetic field type tag unitis fixed to the film by an adhesivewith elasticity at a position that enables communication by electromagnetic coupling between the coil antenna and the auxiliary antenna

Flexible IC tag

Integrated circuit tag

The disclosure prevents, with improved reliability, an IC tag from being broken, while ensuring overall flexibility of the IC tag. The IC tagis provided with a coveringmade of an elastic material, which covers at least the side of the IC tagon which an IC chipis mounted and has a thickness that is larger in its portionthat covers a region about the IC chipthan in its portionthat covers a region outside the region about the IC chip. The coveringis configured in such a way that at least a part of a boundary of the portionof the covering that covers the region about the IC chipand the portionof the covering that covers the region outside the region about the IC chiphas a curved shape.

In order to enhance a shape retaining property of a gasket consisting only of a rubber, prevent damage to a casing for an electronic equipment due to high reactive force of the gasket, and make assembling of the casing easy, a seal structure comprises a gasket installed in a non-adhesion manner between a case and a lid to be interposed in a compressed state when the case and the lid are assembled, and a resin film integrated with the gasket to enhance the shape retaining property of the gasket, the gasket has a portion compressed between the case and the lid when they are assembled, and a portion not compressed between them when assembled and the resin film is integrated with the portion which is not compressed.
