Abstract: A differential thermal analysis of a plurality of metal-resin-containing layers, the resin material amounts of which are known and different from each other, is carried out. Heights of sample peaks observed at one temperature in the differential thermal analysis are measured, and a correlation between the resin material amounts and the sample peak heights is obtained. Then, a differential thermal analysis of a porous metal body is carried out, and a height of a peak observed at the same temperature is measured. An amount of a residual resin material in the porous metal body is obtained based on the measured height and the correlation.

Abstract: The present invention is a method for producing a porous metal body or a method for producing an electrode catalyst, which is capable of simplifying the production process and improving the production efficiency by not requiring a step of immersion in an acid treatment solution. A method for producing a porous metal body according to the present invention comprises: a step for forming a metal resin-containing layer, which contains a metal and a resin that has a lower melting point than the metal, on a base; and a step for obtaining a porous metal body by subjecting the metal resin-containing layer to a heat treatment, thereby sintering the metal and removing the resin from the metal resin-containing layer.
