Abstract

Provided is a film having high crystallinity, transparency, and surface smoothness, a lamination of the film, a sheet of the film, and a laminated body. A film contains vinylidene fluoride-based resin (A) and acrylic-based resin (B). The film has at least one surface with arithmetic mean roughness of 0.1 to 20 nm. The at least one surface has crystal fusion heat of 18 to 40 J/g and a haze value of 3.5 or less, the crystal fusion heat being measured using a differential scanning calorimeter.
