<p>PURPOSE:To mount a paper-type battery low in height and facilitate a battery replacement and am assembly of an IC card device with a paper-type battery mounted on a substrate of a module IC. CONSTITUTION:A paper-type battery 5 is fitted in an opening provided in a substrate 1. A conductive pattern is formed around the opening. An IC, a capacitor, and a connecting terminal 6 are connected by solder 1. If failure of the battery 5 is detected by electrically checking the module IC, the battery can be easily replaced. This module IC is integrally formed out of a resin.</p> |
