Abstract
The method for manufacturing a silver particle-containing composition according to the invention is directed to a method for manufacturing a silver particle-containing composition coated with a fatty acid and includes a step (A) of preparing silver particles coated with a first fatty acid (a) with 3 to 7 carbon atoms, a second fatty acid (b) with 2 to 20 carbon atoms, and a solvent in which the first and second fatty acids can disperse, respectively, a step (B) of adding the silver particles coated with the first fatty acid (a) and the second fatty acid (b) into the solvent, and a step (C) of substituting the second fatty acid (b) for the first fatty acid (a) coating the silver particles after the addition step.
