The present invention relates to a protective film forming sheet (2) comprising a protective film forming film (1) and a release sheet (21) laminated on one or both sides of the protective film forming film (1). The film (1) is characterized in that it has a light transmittance of 72% or more at a wavelength of 1600 nm and a light transmittance of 20% or less at a wavelength of 550 nm. According to the sheet (2) for forming a protective film, it is possible to form a protective film that can realize the inspection of cracks and the like existing on the workpiece or the processed product obtained by processing the workpiece, and can prevent the wear marks existing on the workpiece or the processed product. A protective film that is recognized by the naked eye. |
