(57) A coffee powder filter cup for a coffee machine includes a bottom wall (2) and a peripheral wall (3). The bottom wall (2) has a thickness ranging from 0.7 mm to 1.5 mm and a plurality of apertures (200) formed by a processing laser (L). Each of the apertures (200) has an extending portion (201) that has a length (D) ranging from 0.2 mm to 2.0 mm in an extending direction (E), and two end portions (202) that are connected respectively to opposite ends of the extending portion (201) in the extending direction (E). The extending portion (201) has a width (X) ranging from 0.05 mm to 0.4 mm in a direction that is perpendicular to the extending direction (E). The peripheral wall (3) extends from a periphery of the bottom wall (2) in an upward direction to cooperate with the bottom wall (2) to define a brewing space (W).
