PROBLEM TO BE SOLVED: To provide a propylenic resin composition having an excellent balance between electric conductivity and molding processability, and to provide its molded product. SOLUTION: This propylenic resin composition comprising 100 pts. wt. of propylene-ethylene block copolymer having a MFR of 70 to 500 g/10 min and comprising a propylene homopolymer portion having a MFR of 100 to 800 g/10 min and a (Mw/Mn) of≥2.8 measured by GPC and a propylene-ethylene copolymer portion having a propylene content of 50 to 85 wt. %, and 0.1 to 25 pts. wt. of conductive carbon is characterized by having a MFR of 0.1 to 100 g/10 min and a (ηa/ηb) ratio of≥30, wherein (ηa) is a shear viscosity at a temperature of 200°C and at a shear rate of 10/sec; (ηb) is a shear viscosity at a temperature of 200°C and at a shear rate of 1000/sec.
