The present invention relates to a preparing method for a silver powder, the method comprising a salt reducing step (S2) which comprises: a reaction liquid preparing step (S21) for preparing a reaction liquid containing a silver ion, a reductant, and a phosphate compound; and a precipitating step (S22) for obtaining a silver powder through a reaction of the reaction liquid. Accordingly, the present invention provides a silver powder that has an organic material content of 1.0 wt% or less, a crystallite diameter in the range of 250-600 Å, and a phosphor (P) content in the range of 0.002-0.03 wt%. |
