Metal powders are spread on a feeding belt or a supporting sheet which is continuously fed. Then, the feeding belt or the supporting sheet on which the metal powders have been spread is passed between a pair of rolling rollers to roll them at a required strength of pressure to leave fine gaps between the metal powders adjacent to each other. Thereafter, a resulting metal sheet is passed through a sintering oven to integrate the metal powders to each other so as to form a porous metal sheet having fine pores consisting of the gaps. It is possible to spread the metal powders on the rolling roller directly or a mixture of sublimable fine fragments and the metal powders thereon. Further, it is possible to form a solid metal sheet, namely, a metal sheet having no pores formed thereon by setting the strength of pressure of the rolling roller to a high one. |
