PROBLEM TO BE SOLVED: To provide a resin composition for coating thick metal film that has no occurrence of harmful gas on burning, facilitates the industrial production, causes no swell nor crack even when it is coated thick as well as no sagging nor running away, even when it is coated on vertical faces or ceiling faces. SOLUTION: The resin composition for coating thick metal film comprises (A) a synthetic rubber latex and/or an acryl emulsion that has a glass-transition temperature (Tg) of 0 to 100°C, an acid value of 7 to 60 mg KOH/g, a gel fraction of more than 60 %wt. when soaked in toluene/n-heptane (60/40 weight ratio) solvent, a gel fraction of less than 95 %wt. when soaked in toluene solvent, (B) a filler and (C) a liquid hydrocarbon compound boiling at 300°C or higher.
