To obtain an antifogging film (monolayer or multilayer film) having excellent antifogging properties and farther excellent in a balance between a low temperature dropping property and antifogging durability, transparency, toughness, etc.

This antifogging film is characterized in that the antifogging film is a monolayer or a multilayer film having a layer comprising an ethylene- based copolymer composition composed of a straight-chain low-density polyethylene having 880-930 kg/m3 density obtained by copolymerizing ethylene with a 4-12C α-olefin in the presence of a metallocene-based olefin polymerization catalyst, an antifogging agent and silica powder having 1-6 μm average particle diameter and contains 0.5-5 pts.wt. of the antifogging agent based on 100 pts.wt. of the straight-chain low-density polyethylene and the silica powder in an amount of ≤1/10 that of the antifogging agent in the composition.
