PROBLEM TO BE SOLVED: To obtain a resin material freed from strain resulting from the difference between the coefficients of thermal expansion of the film and the ground and improved in adhesion and surface appearance by using a thermoplastic resin powder having a specified heat of fusion as measured by differential calorimetry. SOLUTION: This material comprises thermoplastic resin powder selected among polyethylene, polypropylene, polystyrene, liquid crystal aromatic polyester (amides), etc., and having a heat of fusion of 25J/g or below (as measured by differential scanning calorimetry), a melt viscosity of 1-10,000 P (as measured at a temperature higher than the melting point of the thermoplastic resin by 10 deg.C and a shear rate of 1,000/sec) and a mean-particle diameter of 10-160μm. This material is optionally mixed with a least one additive selected among a fibrous, powdery, platy or hollow inorganic filler, an antioxidant, a heat stabilizer, an ultraviolet absorber, a lubricant, a mold release, a dye, a pigment- containing colorant, an antistatic agent, a surfactant, a flame retardant, a flame retarding aid and a heat-resistant organic filler.
