Claim:
1. A film for forming, comprising a cyclic olefin-based resin as a main component, wherein the storage modulus at 120° C. is 101 MPa to 3,000 MPa and the storage modulus at 170° C. is 100 MPa or less, wherein the film for forming is a laminated film in which a cyclic olefin layer (layer B) comprising a cyclic olefin-based resin as a main component is laminated on at least one side of a cyclic olefin layer (layer A) comprising a cyclic olefin-based resin as a main component, wherein said layer A comprises a polyethylene-based resin and/or a polypropylene-based resin in an amount of 1 to 40% by mass with respect to 100% by mass of the whole layer A, wherein one surface of said film (surface X) has a surface roughness (SRa) of 2 nm to less than 50 nm and the other surface (surface Y) has a surface roughness (SRa) of 50 nm to 1,000 nm, and wherein one surface of said film (surface X) has a surface roughness (SRmax) of 20 nm to less than 500 nm and the other surface (surface Y) has a surface roughness (SRmax) of 500 nm to 10,000 nm.
