Abstract
Abstract An IC card mooule includes a substrate 12 one side of which is provided with a connection terminal 7; and a resin-sealed semiconductor IC 11 which has been previously sealed by a resin. This connection terminal and the resin sealed semiconductor IC are electrically connected to each other and are molded with a molding resin 17 in such a manner that they are covered with the molding resin so as to prevent at least the electrically-connected portion 16 between them from being allowed to appear. Accordingly, reliable modules can be efficiently manufactured, and such reliable modules can be readily mounted on IC card substrates.
