PROBLEM TO BE SOLVED: To provide a drainage funnel capable of smoothly draining a large amount of liquid and facilitating daily cleaning work. A drainage funnel (1) including an inner funnel (2) for receiving drainage, an outer funnel (3), and a holder (4) for holding the inner funnel inside the outer funnel, wherein the inner funnel is drainage. Inner pipe portion for discharging the inner pipe portion, an inner body portion having a diameter larger than the inner pipe portion, and an inner diameter expansion connecting the inner pipe portion and the inner body portion while expanding the diameter from the inner pipe portion toward the inner body portion. The outer funnel includes an outer tube portion, an outer body portion having a diameter larger than that of the outer tube portion, and an outer tube portion and an outer body portion while increasing in diameter from the outer tube portion toward the outer body portion. A drainage funnel characterized in that a gap is formed between the inner body portion and the outer body portion, and the outer diameter portion is connected to the outer diameter portion.
