An infusion coffee maker, comprising:

• a drip cup, being substantially conical in shape and having a bottom side, said bottom side being conical and having a through hole in the center thereof, said drip cup further having a extended wall extending from the periphery of said bottom side, said extended wall being circumferentially provided with a plurality of spaced, vertically elongated holes and having a plurality of spaced legs extending from the bottom end thereof;
• a filter assembly, including an annular body, a support frame connected to said annular body, and a mesh element mounted on said annular body and said support frame, said annular body being provided with a plurality of ribs on the outer periphery thereof;
• a retaining plate, including a ferrule of a diameter slightly smaller than that of the extended wall, a positioning rib element disposed within said ferrule such that rib portions of said positioning rib element are integrally connected to the inner periphery of said ferrule, said positioning rib element having a hole in the center, said ferrule having a plurality of retaining posts on the outer periphery, and said retaining plate further having a plurality of slots for receiving said legs of said drip cup;
