The filter medium according to an embodiment of the present invention is provided with: second porous supporting bodies stacked in order on the top and bottom portions, respectively, of a first porous supporting body; and a nanofiber web, wherein the filter medium having a flow path through which a filtered liquid filtered by the nanofiber web flows toward the first supporting body formed therein is realized such that the first supporting body, the second supporting bodies, and the nanofiber web satisfy predetermined conditions for the basis weight and thickness of each layer. Accordingly, in the filter medium, deformation and damage to the shape and structure of the filter medium during water treatment is minimized, the filtering efficiency is excellent, and a flow path is secured without difficulty, and thus a high flow rate can be achieved. Also, the filter medium has an extended usage period due to the excellent durability of the filter medium even under the high pressure applied during a backwashing process. Therefore, the filter medium can be diversely applied in various water treatment fields.
