PROBLEM TO BE SOLVED: To provide a conductive paste capable of forming a conductor pattern with high conductivity inexpensively, and to provide a conductor pattern with high conductivity inexpensively. SOLUTION: A conductive paste contains silver-coated copper powder and a binder resin with a glass transition temperature (Tg) of 35-170°C, wherein at least a part of a surface of the copper powder is coated with silver. An average particle diameter of the copper powder is preferably 0.001-50μm. The binder resin is preferably a cellulose derivative. An amount of the silver coating the surface of the copper powder is preferably 0.1-300 pts.wt. per 100 pts.wt. of the copper powder. After the conductive paste is printed on a base material in a predetermined shape, a conductor pattern is formed preferably by pressing or wet-heat treatment. COPYRIGHT: (C)2010,JPO&INPIT |
