Zusammenfassung:PROBLEM TO BE SOLVED: To provide a thermoplastic resin film having excellent electroconductivity even with a small amount of an electroconductive material. SOLUTION: The electroconductive thermoplastic resin film is obtained by mixing a thermoplastic resin with fine carbon fibers having a fiber diameter of 0.001-0.5 μm and a fiber length of 0.1-100 μm, and has a volume resistance value at a mixed volume ratio of the above thermoplastic resin to the fine carbon fibers of 50/50 of 0.01-0.03 Ωcm and, simultaneously a volume resistance value at the mixed volume ratio of 90/10 of 0.1 to 0.5 Ωcm.
