PROBLEM TO BE SOLVED: To provide a resin composition which is improved in fluidity, stiffness and impact resistance and therefore can achieve the reduction in wall thickness of a resin product for automotive interior/exterior applications comprising a polypropylene resin, and to provide the resin product produced from the resin composition. SOLUTION: This resin composition comprises: 30-65 mass% of an ethylene-propylene block copolymer having a melt flow rate of 60-120 g/10 minutes and a Charpy impact strength of 3 kJ/m<SP>2</SP>or more; 0-25 mass% of a homopolypropylene resin having a melt flow rate of 10 g/10 minutes or more and a modulus of elasticity of 2,000 MPa or more; 5-20 mass% of an ethylene-α-olefin copolymer rubber having Mooney viscosity of 20-75 or a styrene-ethylene-butylene-styrene copolymer having a styrene component content of 15-30 mass%; and 23-37 mass% of talc having an average particle diameter of 8μm or less.
