To provide: a resin composition which is capable of easily forming a film that has excellent thermoelectric conversion characteristics and flexibility; and a film having excellent thermoelectric conversion characteristics and flexibility, which is formed from the resin composition. A thermoelectric conversion material-containing resin composition is configured to contain (A) an insulating resin, (B) an inorganic thermoelectric conversion material, and (C) a charge transport material. A film is formed using this thermoelectric conversion material-containing resin composition by a well known method. It is preferable that the inorganic thermoelectric conversion material (B) is in the form of fine tubes or wires. Single-walled carbon nanotubes are particularly preferable as the inorganic thermoelectric conversion material (B).
