Zusammenfassung:	Provided are a silver powder and a method for producing the same. The method for producing the silver powder according to the present invention comprises: a first surface smoothing step in which fine silver particles, each having an internal void, are caused to mechanically collide with one another; a fine powder removal step in which a fine powder is removed while using a high pressure air stream to disperse the fine silver particles after the first surface smoothing step; and a second surface smoothing step in which the fine silver particles after the fine powder removal step are caused to mechanically collide with one another.
