Abstract

There is shown a propylene resin composition including 100 parts by weight of (A) a propylene resin and 0.05 to 0.5 part by weight of (B) a nucleating agent containing an organophosphoric ester compound represented by the formula (B1) and at least one kind selected from aliphatic carboxylic acids and derivatives thereof and containing an alkali metal element as an essential component, wherein MFR is 11 to 100 g/10 min, the crystalline melting point is 140 to 155° C., and in an elution curve determined by a temperature rising elution fractionation chromatograph (TREF), the elution quantity Wp1 (% by weight) in a temperature range higher than the main elution peak temperature Tp and the elution quantity Wp2 (% by weight) in a temperature range not higher than 10° C. are each in a specific range.
