  • Publication number: 20210040638
    Abstract: A method for producing a metal porous body includes the steps of: performing electrical conduction treatment on a surface of a skeleton of a sheet-like resin porous body having the skeleton with a three-dimensional network structure, to obtain a conductive resin porous body having a conductive layer; performing electroplating treatment on a surface of a skeleton of the conductive resin porous body to obtain a plated resin porous body having a metal plating layer; and performing treatment of removing at least the resin porous body from the plated resin porous body to obtain a metal porous body. In the electroplating treatment, power is supplied to a rotation shaft of a rotating electrode roller while a contact surface of a power supply brush composed of a sintered body is brought into sliding contact with the rotation shaft, with a lubricant, not containing conductive metal powder, interposed therebetween.

In the electroplating treatment, power was supplied to a rotation shaft of a rotating electrode roller by bringing a power supply brush formed by a material containing carbon as a main component into sliding contact with the rotation shaft.
