PROBLEM TO BE SOLVED: To provide an intermediate coating film having an excellent performance of chipping, peeling or the like, while holding various performances such as topcoating suitability and sanding suitability, and to provide a coated material having the intermediate coating film. SOLUTION: An intermediate coating film has the ratio (tanδ) of an imaginary number part (loss modulus) of complex elastic modulus at measured frequency of 11 Hz at -50 to -20 deg.C to a real number part (storage modulus) thereof of 0.015-0.05, and a main dispersion in complex elastic modulus measured at the measuring frequency of 11 Hz of 30-150 deg.C. A coated material has the intermediate coating film.
