The present invention relates to a graphene-polyimide composite film comprising multi-layer graphene particles and a production method thereof. According to the method for producing the graphene-polyimide composite film, it is possible not only to exhibit high thermal conductivity of graphene while maintaining insulating properties of polyimide, thereby enabling production of high heat dissipation graphene-polyimide composite films having shielding properties with light transmittance close to 0%. In addition, it is possible to improve dispersibility of raw materials during the production of the composite film by the production method, thereby reducing precipitation. Accordingly, the graphene-polyimide composite film of the present invention has excellent insulating properties, heat dissipation properties, and shielding properties, and can be effectively used in electronic materials such as heat-resistant coating agents, insulating films, semiconductors, and electrode protective films.
