PROBLEM TO BE SOLVED: To provide an easy-to-handle drain grating, which facilitates removal of collected garbage in cleaning of the drain grating, by guiding the garbage such as hair to a lower step (bottom), which is a center of the drain grating, and collecting the garbage in an intensively accumulated state, while preventing the garbage from getting entangled with nor adhering to a handgrip portion, even when drainage amount is small. SOLUTION: This drain grating 1 includes an annular flange 2, an upper portion 10 and the lower portion 11. The flange 2 and the upper portion 10 are continuously constituted via an upper peripheral wall 6 while the upper and lower portions 10 and 11 are continuously constituted via a lower peripheral wall 12. A handgrip portion 4 is provided rising in a position to recede to the inside with respect to the outer edge of the flange 2 and a protrusive portion 16 is provided rising from the upper portion 10 to a position higher than the flange 2 on the inner surface side of the handgrip portion 4.
