PROBLEM TO BE SOLVED: To provide a polypropylene resin composition, which depends on forming and crystallization conditions to a lesser extent, is solidified at a stably fast rate, and has good formability. SOLUTION: This polypropylene resin composition contains 100 pts.wt. of a component A and 2 to 100 pts.wt. of a component B, wherein the component A is a propylene polymer(PP) satisfying the following conditions (1) and (2): (1) steric regularity of 97% or more, and (2) weight-average molecular weight of 10,000 to 1,000,000, and the component B is an ethylene/propylene copolymer(EPR) satisfying the following conditions (3) to (6): (3) propylene content of 20 to 80 mol%, (4) uniform compositional distribution with molecular weight, biasing 10% or less from the average composition, (5) weight-average molecular weight of 10,000 to 1,000,000, and (6) the component having a molecular weight of 10,000 or less accounting for 10% or less.
