A laminated film including a thermoplastic resin film and an laminated layer that is formed on at least one side of the thermoplastic resin film and comprises (A) a composition, (B) an epoxy crosslinking agent and (C) an acrylic resin having an alkyl chain of 18 to 25 carbon atoms is characterized in that the composition (A) is a composition containing at least a polythiophene and a polyanion and/or a composition containing a polythiophene derivative and a polyanion, the laminated layer contains 15 to 100 parts by weight of the acrylic resin (C) having an alkyl chain of 18 to 25 carbon atoms based on 100 parts by weight of the sum of the composition (A) and the crosslinking agent (B) and/or its reaction product, at least one side of the laminated film has a three-dimensional average surface roughness (SRa) of 3 to 50 nm, and the laminated film contains less than 10 internal contaminant particles with an average particle size of at least 100 &#x3bc;m per 1 m, so that it has high level of electrical conductivity, good releasability and water resistance, and also has oligomer precipitation-preventing properties during heating.
