Abstract: The metering device includes a base having a first surface which borders on an infeed passage for a gaseous or fluid medium, a second surface which borders on a passage through which a viscous or pasty mass flows, and a recess communicating the two surfaces. The metering device also has a metering element which is made of a fluid-permeable or gas-permeable material that mates at least partly into the recess in the base. The metering element forms a fluid-conducting element having hollow spaces which form pores. The surface of the metering element facing the flow of viscous or pasty mass includes a coating by which the relevant pore diameter can be reduced such that an entry of the viscous or pasty mass into the interior of the metering element can be avoided.
