POROUS METAL HAVING EXCELLENT DUCTILITY, AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a porous metal which has excellent ductility, and becomes the stock for producing a filter for high temperature use, a filter for an air cleaner and an electrode substrate of an alkali secondary battery, and to provide a production method therefor. SOLUTION: The metal is obtained by forming a metal plated layer at least on the surface of an internal skelton of a blowing porous metal with a three- dimensional network structure formed of continuous vacancies opened to the surface and continued to vacancies at the inside, and a skelton. The roughness of the surface of the metal plated layer formed at least on the surface of the internal skelton is 0.05 to 5μm by a center line mean roughness.
