ID label, ID tag, and ID card
First Claim
1. An article comprising:
- an antenna;
an integrated circuit device operationally connected to the antenna; and
a filling layer provided around the antenna,wherein an anisotropic conductive film is included in a connection between the integrated circuit device and the antenna,wherein a resin is used as the filling layer, and wherein a filler is included in the filling layer.

Abstract
In commercial products to which a non-contact type or contact type ID label or ID tag is attached and ID cards, there is fear that, due to a difference between coefficients of thermal expansion between an antenna for communication and a resin provided around the antenna, stress is applied to the resin with the larger coefficient of thermal expansion to break the resin. This contributes to a decrease in manufacturing yield, lifetime, and reliability of an ID label or the like. In an article such as an ID label, an ID tag, and an ID card according to the present invention, a filler is included in a filling layer provided around an antenna forming an ID label, an ID tag, and an ID card so that the difference in coefficient of thermal expansion between the antenna and the filling layer can be reduced. This makes it possible to ease generation of stress due to the difference in coefficient of thermal expansion and prevent peeling and cracks of the filling layer.
