The present invention relates to a pot-shaped permanent filter insert for use in an espresso machine, the insert comprising a filter base plate which substantially forms the bottom of the pot and is penetrated by a plurality of filter openings substantially in the flow direction of the medium to be filtered and comprises a frame surrounding the filter base plate, and a pot wall which is substantially arranged on the edge of the filter base plate and transversely extends away from the filter base plate to form a coffee receiving portion, the permanent filter insert being made of a plurality of parts in that the lower edge portion of the pot wall is substantially secured to the outer edge of the filter base plate. Furthermore, the lower edge portion of the pot wall and the filter base plate are interconnected by an injection-molded plastic connection, a frame being injection-molded substantially around the outer edge of the filter base plate, interconnecting the frame and the filter base plate and the pot wall.
