To provide a transparent vapor deposition polyester film excellent in the vapor deposition adhesion of metal oxide and also excellent in retort resistance and blocking resistance.

An easy adhesive film mainly constituted of (A) fine particles with an average particle size of 20-150 nm comprising a copolyester with a second transition point of 40-80°C obtained by copolymerizing 2-8 mol.% of a dicarboxylic acid component having a metal base and (B) fine particles with an average particle size of 20-150 nm comprising an acrylic copolymer with a second transition point of 20-60°C is provided on at least the single surface of a polyester film and this easy adhesive film is characterized that thickness is 5-200 nm, surface roughness (Ra) is 20-40 mm, surface haze is 1.5% or less and the total haze per total film thickness of 12 μm is 4.0% or less.
