However, in the cutting operation of the surface protective film, the adhesive exposed from the cut surface adheres to the surface of the other protective film, hindering the inspection of the product, and the adhesiveness becomes a hindrance when the product is transported. Therefore, as one of the above disadvantages, it is proposed to provide a contamination-preventing layer and a surface-preserving film on one side of the protective film (for example, refer to Patent Document 7). However, it has been clarified that there is a problem that the above-mentioned side has an increase in production steps and an increase in cost.
