<；P>；PROBLEM TO BE SOLVED: To provide a laminate film which can maintain anti-fogging property even when being exposed under high-temperature environment, or recover the anti-fogging property if the environmental temperature lowers, even when the anti-fogging property once deteriorates. <；P>；SOLUTION: Provided is a laminate film composed of at least three layers satisfying the following conditions. When one front layer is made to be A-layer, the other front layer is B-layer, and other layers positioned between the A-layer and the B-layer is C-layer, (1) the thickness of the C-layer is 50 to 90% of the thickness of whole layer, (2) C<；SB>；VA<；/SB>；/T<；SB>；VA<；/SB>；is 0.1 and more and 1.5 or less, (3) T<；SB>；VA<；/SB>；is 0.1% or more and 7.0% or less, (4) the concentration of a nonionic surfactant having a melting point of 40°；C or more of whole layer is 2.0% or more and 5.0% or less, and (5) (the concentration of the nonionic surfactant of the A-layer)/(the concentration of the nonionic surfactant of the whole layer) is 0.2 or more and 5.0 or less. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
