Abstract
A method of manufacturing a porous metal sheet having pores forming a pattern, comprising the steps of supplying metal powders to a peripheral surface, of at least one pattern roller of a pair of rollers, on which a pattern including a large number of concaves is formed; dropping metal powders to the concaves and accumulating metal powders on the peripheral surface of the pattern roller except the concaves; and rolling directly the metal powders accumulated on the peripheral surface of the pattern roller by rotating a pair of the rollers. It is preferable to laminate porous metal sheets or solid metal sheets manufactured by a method other than the above-described method on the metal sheet manufactured by the above-described method.
