METHOD FOR PREPARING CONDUCTIVE PATTERN AND CONDUCTIVE PATTERN PREPARED BY THE METHOD

摘要

Provided is a method for preparing a conductive pattern, which is capable of sufficiently blackening the conductive pattern, reducing sheet resistance, improving productivity, and reducing manufacturing costs. The conductive pattern preparation method comprises the steps of: forming a conductive pattern(22) on a base material(21); and soaking(or digesting) the conductive pattern in aqueous solution that contains reductive metal ions for oxidizing the surface of the conductive pattern(22), thereby blackening the surface of the conductive pattern(22) to form a blackened layer(23). Preferably, the conductive pattern(22) is a silver conductive pattern containing silver powder. The silver conductive pattern is obtained by directly printing a conductive paste containing silver powder onto the base material(21).
