The function plate with passage openings, for use with gas and liquid media, has a carrier structure with a bonded contact layer. The contact layer is porous, and permeable to gases and liquids, with capillaries which match the passage openings for a flow through the structure. At least one additional secondary layer is applied over the contact layer of the same or different porous material and/or an additional porous layer is applied on the other side of the carrier structure. The contact, secondary and/or additional layers are of ceramic or metal-based materials. The cross section of the capillaries can be varied according to requirements. The carrier structure of the function plate is a sieve, and especially with gap openings. The surface aligned against the media flow direction carries a micro-porous contact layer with a layer thickness of at least 20 micro m and preferably 0.1 mm. An Independent claim is included for the production of a function plate where finely distributed particles are applied to the carrier structure together with the particles to form the contact, secondary and/or additional layers. After successful cladding, they are removed from the contact, secondary and/or additional layers.
