METHOD FOR PRODUCING POROUS METAL BODY AND POROUS METAL BODY

摘要

A method for producing a porous metallic body at least includes a step of forming an electrically conductive coating layer on a surface of a skeleton of a three-dimensional network resin having a continuous pore by coating the surface with a coating material containing a carbon powder having a volume-average particle size of 10 μm or less and at least one fine powder having a volume-average particle size of 10 μm or less and selected from the group consisting of metal fine powders and metal oxide fine powders; a step of forming at least one metal plating layer; and a step of performing a heat treatment to remove the three-dimensional network resin and to cause reduction and thermal diffusion in the at least one metal or metal oxide fine powder and the at least one metal plating layer.
