ABSTRACT:
Disclosed are conductive powder having a packing density of 68% by volume or more with a relative value preferably comprising 60 to 92% by weight of roughly spherical and silver-plated copper powder part of the surface of which has been coated with 3 to 30% by weight of silver based on an amount of roughly spherical copper powder with exposing at least a surface of a portion of an alloy of copper with silver, and the surface of which is coated with 0.02 to 1.0% by weight of an aliphatic acid based on an amount of the roughly spherical and silver-plated copper powder, and 8 to 40% by weight of silver powder, and a method for preparing the same.
