Title: Method for the production of a metal membrane filter

Abstract: The invention relates to a metal membrane filter (1) and to a method and apparatus for the production thereof. The metal membrane filter (1) has rectilinear, cylindrical filter pores (2), which are arranged statistically distributed on the metal membrane filter surface (3) in a density of from a single filter pore (2) per cm.sup.2 up to 10.sup.7 filter pores (2) per cm.sup.2. The average diameter of the filter pores (2) is uniform for all filter pores (2) and is from a few tens of nm up to several micrometers. The metal membrane filter (1) comprises a metal electro-deposited with rectilinear, cylindrical filter pores (2) or a correspondingly electro-deposited metal alloy.
