Non-contact information communication apparatus

This application is based upon and claims the benefit of priority from the prior Japanese Patent Applications No. 2002-99074, filed on Apr. 1, 2002, the entire contents of which are incorporated herein by reference. A non-contact information communication apparatus according to the present invention has a bare IC and a sheet capacitor implemented on substrate , and an antenna coil of vortical circle shape formed on the substrate so as to enclose at least portion of the bare IC and the sheet capacitor . Because the number of turns of the antenna coil is set to 7-10, the outer size of the antenna coil can be set to be equal to or smaller than one yen size. Each of the substrate , the antenna coil , the bare IC and the sheet capacitor is thinned, and the thickness of the entire apparatus is set to be equal to or thinner than 100 m. Because of this, the apparatus can be much thinner than the conventional apparatus, thereby using it in various field.
