To provide a wet process manufacturing method for silver powder of a coarse grain size having excellent low temperature sintering characteristics and electric conductivity by using a wet process reduction method and particularly suppressing a manufacturing cost.
The wet process reduction method to cause contact mixing of a silver ion-containing solution and a reducing agent-containing solution is used and the silver ion-containing solution includes an aqueous silver nitrate solution. The wet process manufacturing method for the silver powder including one or more selected from the group consisting of an ascorbic acid, isomer of the ascorbic acid, sulfate having reduction ability, and sulfite having reduction ability which are dissolved into water is employed.
