PROBLEM TO BE SOLVED: To provide a propylene resin excellent in rigidity, heat resistance, moldability or the like. SOLUTION: The objective propylene resin meets the equation: FM>=1,300 tan-1 (1.31×PI) [wherein PI is a product of multiplying the reciprocal of the storage elastic modulus value (unit: Pa) at the intersection point Gc of a frequencyωdependent curve G' (ω) of storage elastic modulus and a frequencyωdependent curve G'' (ω) of less elastic modulus by dynamic viscoelasticity measurement by 105; and FM (unit: MPa) is a modulus in flexure according to JIS K7203].
