PROBLEM TO BE SOLVED: To provide a sheet obtained by laminate processing base material woven by warp and weft wire material, hard to be cut off by such as hands because of strength of the wire material even when cuts by broken lines are made thereto.SOLUTION: A sheet comprising an opening planned portion according to the present invention comprises the opening planned portion (5) for planting a plant to a sheet material (4) obtained by laminate processing base material (3) woven by warp wire material (1) and weft wire material (2). The opening planned portion (5) is sectioned by a pair of inside broken line (6a) and outside broken line (6b). The inside broken line (6a) and outside broken line (6b) are respectively cut parts (7a, 7b) and uncut parts (8a, 8b) of the warp wire material (1) and the weft wire material (2), alternately aligned with each other. And, for the pair of the inside broken line (6a) and outside broken line (6b), length and interval of the broken lines are set so that at the inside between both broken lines, the warp wire material (1) and weft wire material (2) of the sheet material (4) are cut.
