IC card and method of manufacturing the same
First Claim
1. An IC card, comprising an insulating core sheet formed of an insulating material and having a main surface, a bottom surface, and at least one through-hole, at least one semiconductor IC chip received within said hole, and having a main surface and a bottom surface, and at least one electrode, and at least one conductive layer pattern deposited on said core sheet, said conductive layer being connected to said electrode;
- and said semiconductor IC chip being thinner than said core sheet and including at least one conductive projection which is formed on said electrode and has top and side surfaces, said semiconductor IC chip being embedded in said core sheet by the insulating material so that the top surface of said conductive projection and the bottom surface of said IC chip are flush with the main surface and bottom surface of the core sheet, respectively;
said conductive layer pattern being deposited on the main surface of said core sheet; and
the side surface of said conductive projection and only the peripheral portion of the main surface of said IC chip being covered with the material of said core sheet and said conductive layer pattern being connected with said conductive projection at said top surface.

Abstract
An IC card comprises a thermoplastic resin core sheet and an IC chip bearing a conductive projection formed on an electrode of the IC chip, the IC chip being embedded in the core sheet in such a manner that the exposed top surface of the conductive projection is made flush with the main surface of the core sheet. A conductive layer pattern formed on the main surface of the core sheet is extended for contact with the exposed top surface.
