The purpose of the present invention is to provide, at low cost, a porous metal body which has more excellent corrosion resistance and is able to be utilized for electrodes of fuel cells. A porous metal body which contains nickel (Ni), tin (Sn) and chromium (Cr) and has a three-dimensional network structure. The content ratio of the tin is from 10% by mass to 25% by mass (inclusive), and the content ratio of the chromium is from 1% by mass to 10% by mass (inclusive). A cross-section of the skeleton of this porous metal body contains a solid solution phase of chromium, nickel and tin. This solid solution phase contains a solid solution phase of chromium and trinickel tin (Ni3Sn) having a chromium content ratio in the solid solution phase of 2% by mass or less, but does not contain a solid solution phase other than the solid solution phase of chromium and trinickel tin (Ni3Sn), which has a chromium content ratio in the solid solution phase of less than 1.5% by mass.
