PROBLEM TO BE SOLVED: To provide: a printed wiring board which is reducible in resistance value; a wiring manufacturing method; and a conductive paste. SOLUTION: A wiring pattern printed using a first conductive paste obtained by kneading silver powder is covered with a second conductive paste obtained by kneading carbon powder and metal powder finer than the carbon powder with each other. Further, the second conductive paste is obtained by kneading fine particles of metal which hardly causes ion migration as compared with silver with the carbon powder. The metal is one or a plurality of nickel, copper, palladium, and cobalt, an alloy thereof, or a mixture thereof. COPYRIGHT: (C)2010,JPO&INPIT |
