[Action]

 Since the release sheet 20 is partially cut along the scoring line 21 in the mesh sheet with an adhesive material of the present invention, a discontinuous portion is partially generated in the single release sheet 20.

Bending deformation (curl) due to a difference in expansion / contraction ratio between the mesh fabric 1 that is relatively easy to adapt to deformation in the expansion / contraction direction and the release sheet 20 that is relatively difficult to adapt to When it occurs, the discontinuity of the release sheet 20 that is temporarily entirely adhered to the back surface of the mesh fabric 1 via the adhesive layer 2 makes it possible to appropriately adjust the expansion or contraction direction, and to bend the curve. Can be prevented.
