Provided is a laminated thermoplastic resin film that is excellent in adhesion, blocking resistance, and antistatic properties, and particularly excellent in stability of optical properties when used as a base film for a near-infrared absorbing film. A laminated thermoplastic resin film having an adhesion modified layer made of a resin composition mainly comprising a copolyester resin and a polyurethane resin on one side or both sides of a thermoplastic resin film, The adhesion modified layer has a structure in which the polyester phase 1 and the polyurethane phase 2 are microphase-separated or nanophase-separated, and when the scanning probe microscope is observed in the phase measurement mode, the following (1) The area ratio of the polyester phase on the surface of the adhesion modified layer defined by the formula is 35% or more and less than 90% in a measurement area of 5 μm × 5 μm, and contains a π-electron conjugated conductive polymer on one side It is a laminated thermoplastic resin film in which an antistatic layer is laminated.
