PROBLEM TO BE SOLVED: To make it possible to easily remove a separator from a tacky adhesive surface and a non-tacky adhesive surface forming sheet with weak force by partially sticking the non-tacky adhesive surface forming sheet to the tacky adhesive surface of a tacky adhesive material and covering this non-tacky adhesive surface forming sheet with the separator. SOLUTION: The non-tacky adhesive surface forming sheet 2 is partially stuck to the tacky adhesive surface 1c of the sheet-like tacky adhesive material 1 having the tacky adhesive surface 1c on one surface. The separator 3 is stuck over the entire surface of the tacky adhesive material 1 so as to cover the non-tacky adhesive surface forming sheet 2, by which the masking material is formed. The tacky adhesive material 1 has a sheet-like base material 1b and a tacky adhesive layer 1a adhered to the entire surface of the one surface of the base material 1b. When the non-tacky adhesive surface forming sheet 2 is stuck partially to the tacky adhesive material 1, the tacky adhesive surface 1c of the tacky adhesive material 1 is divided to a portion covered by the non-tacky adhesive surface forming sheet 2 and a portion not covered by the same. The portion not covered by the non-tacky adhesive surface forming sheet 2 is stick to a work, by which the tacky adhesive material 1 is stuck to the work. |
