Zusammenfassung:	To suppress a decrease over time in the adhesion of ink to a thermoplastic resin film, provided is a thermoplastic resin film containing an inorganic filler, wherein at least one surface of the thermoplastic resin film satisfies the following formula (1) and formula (2):0.8≤S1/S0≤1.0 (1)3.0≤S0 (2)wherein S0 represents an oxygen atom concentration (atm %) before a washing treatment (A) is carried out, S1 represents the oxygen atom concentration (atm %) after the washing treatment (A) is carried out, the oxygen atom concentration is a ratio of the number of oxygen atoms to a sum of the number of oxygen atoms and the number of carbon atoms measured by XPS (X-ray photoelectron spectroscopy) (number of oxygen atoms/(number of oxygen atoms+number of carbon atoms)), and the washing treatment (A) is a washing treatment carried out using distilled water.
