摘要： A porous metal member composed of an alloy at least containing nickel and tungsten is provided. The alloy may contain 50 to 80 wt % of nickel and 20 to 50 wt % of tungsten and may further contain 10 wt % or less of phosphorus and/or 10 wt % or less of boron. Such a porous metal member can be produced by, for example, making a porous base such as a urethane foam be electrically conductive, forming an alloy film containing nickel and tungsten, then removing the porous base from the alloy film, and subsequently reducing the alloy.

摘要： A porous resin article having a three-dimensional network structure is used. A resin molded body at least the surface of which has been subjected to conductive treatment is plated with aluminum in a molten salt bath to form an aluminum structure, thus forming a porous aluminum that includes an aluminum layer having a thickness in the range of 1 to 100 μm, has an aluminum purity of 98.0% or more and a carbon content of 1.0% or more and 2% or less, and contains inevitable impurities as the balance. Even with a porous resin molded body having a three-dimensional network structure, this allows the surface of the porous resin molded body to be plated with aluminum, thus forming a high-purity aluminum structure having a uniform thick film.
