ABSTRACT:
A method for manufacturing a porous thin foil at least comprising a process for folding a first metallic plate having a large elongation percentage in half and putting a second metallic plate having a small elongation percentage between the folds of the folded first metallic plate, a process for cold-rolling a laminate of the folded first metallic plate and the second metallic plate put between the folds of the folded first metallic plate, and a process for separating a porous thin foil formed from the second metallic plate from the first metallic plate.
The porous thin foil thus formed has numerous elongate fissures extending perpendicular to the direction of rolling, and hence the porous thin foil has a fibrous construction.
