Abstract
A laminated film can be easily used by general users and can prevent entry of foreign substances and air bubbles between the attached surfaces even when the film is manually attached in a typical room environment in which foreign substances such as dust are floating. A film attachment method using such a laminated film is also disclosed. In an embodiment, the laminated film includes: a first surface protective film; a foreign-substance-removing adhesive layer; a foreign-substance-removing film; an integrating adhesive layer; a second surface protective film; a substrate-attaching adhesive layer; and a functional film, the substrate-attaching adhesive layer exhibiting a higher bond strength with the functional film than with the second surface protective film.
