PROBLEM TO BE SOLVED: To find a material and a method used for a suitable surface treatment and a suitable sealing treatment, and to provide a method for manufacturing a mesh-like sheet which suppresses a manufacturing cost. SOLUTION: This is a method for manufacturing a mesh-like sheet 11 in which at least one surface is mold-released and is composed of weft threads 12a and warp threads 12b. The mesh-like sheet 11 is characterized in that the sealing treatment at the intersection 12c of 12a and the warp 12b and the mold release treatment are simultaneously performed using the same treatment liquid containing at least a silicone-based resin or a fluorine-based resin. A manufacturing method, a mesh-like sheet 11 manufactured by using the manufacturing method, and a mesh-like sheet roll obtained by winding the mesh-like sheet 11 without using a release sheet.
