Claim:
1. An apparatus for producing a composite film having a linearly-scratched, thin metal film and a plastic film, the apparatus comprising: (a) a first, upstream-side pattern roll having large numbers of fine, high-hardness particles on the surface, and arranged on one side of said composite film, and inclined with respect to the transverse direction of said composite film; (b) a second, downstream-side pattern roll having large numbers of fine, high-hardness particles on the surface, and arranged on the same side as said first pattern roll with respect to the composite film, and inclined to a different side from that of said first pattern roll with respect to the transverse direction of said composite film; and (c) first and second push rolls arranged near said first and second pattern rolls on the opposite side to said first and second pattern rolls with respect to said composite film; said thin metal film pushed by said first and second push rolls being brought into sliding contact with said first and second pattern rolls, and the positions and/or angles of said first and second push rolls to said first and second pattern rolls being adjusted, to form large numbers of substantially parallel, intermittent, linear scratches in plural directions on said thin metal film, while preventing the lateral movement of said composite film.
