<p><P>PROBLEM TO BE SOLVED: To provide a conductive sheet having good moldability, transparency and water resistance, having conductivity of an antistatic level even after molded into a product such as a tray and a carrier tape, not causing disadvantageous states such as electric short-circuit, harming an electronic component that is contained and failure in seal with other material such as a cover tape, and also favorable in environmental aspects because of reduced un-biodegradable residues in discarding it. <P>SOLUTION: The biodegradable conductive sheet comprises, on at least one surface of a base material sheet consisting of a polylactic acid based biodegradable resin, a conductive coating film formed from a dispersion that has a conductive substance dispersed in a biodegradable resin emulsion. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
