Abstract
There is provided an inexpensive silver particle dispersing solution being usable as a slurry for ink jet, a method for producing the same, and a method for producing a conductive film using the silver particle dispersing solution. In a silver particle dispersing solution containing a silver powder and a solvent, the silver powder has an average primary particle diameter (D) of 0.15 to 0.5 μm, and the ratio (D/D) of a particle diameter (D), which corresponds to 50% of accumulation in volume-based cumulative distribution of the silver powder, to the average primary particle diameter (D) is not less than 1.7, the silver powder having a fatty acid adhered to the surface thereof, and the solvent containing a monohydric higher alcohol having a carbon number of 6 to 12, butyl carbitol or butyl carbitol acetate as the main component thereof.
