<p>PURPOSE:To obtain a memory card preventing the breakage of stored data and an IC even with the occurrence of a static electricity inside by peripherally providing a conductive wire on a printed board separately from the other wiring so that it surrounds an internal wiring of the printed board. CONSTITUTION:A conductive wire 11 is peripherally formed on a printed board 1 in the range of 6mm or less inside from the periphery thereof. Since the conductive wire 11 peripherally formed on the printed board 1 must be electrically connected, for example, it is connected by using the rear of the printed board 1, or it is connected with a jumper wire via through holes provided on the printed board 1. On the other hand, terminals 12 are formed on the both ends of the conductive wire 11 outside input terminals 8 of the printed board 1 to be electrically connected to a chassis of a reception-side device through connectors. In this manner, by providing the conductive wire 11 which is a shielding wire, the occurrence of a static electricity inside and the breakage of data and an IC caused by an electric discharge are prevented.</p> |
