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.
