PROBLEM TO BE SOLVED: To provide a method for manufacturing a conductive film, capable of achieving an efficient progress of reduction of a metal oxide into a metal and yielding a conductive film which exhibits excellent adhesion to a substrate, and to provide a printed wiring board.SOLUTION: The method for manufacturing a conductive film includes: a step of applying a dispersion liquid containing metal oxide particles on a substrate 10 to form a precursor film 12 containing the particles; and a step of irradiating the precursor film with a continuous oscillation laser beam 16 while relatively scanning the film, so as to reduce the metal oxide in an irradiated area by the continuous oscillation laser beam to form a metal-containing conductive film 18. The scanning speed is 1.0 m/s or more; the laser power of the continuous oscillation laser beam is 6.0 W or more; and the irradiation time per one point on the precursor film surface is 1.0 μs or more. |
