Abstract
The invention provides a substantially flat sieve material of metal with sieve apertures, in particular sieve apertures with microdimensions. The sieve apertures comprise at least one passage in the plane of the sieve material parallel to a main surface, while the inlet and outlet can open onto the same main surface or a different main surface. The invention furthermore provides a method for the production of such sieve material by means of electroforming techniques in which a sacrificial material is used.
