PROBLEM TO BE SOLVED: To provide a foamed polypropylenic film obtained by an air-cooled inflation forming method, composed of uniform and fine foamed cells and having excellent appearance and formability. SOLUTION: The foamed polypropylenic film is produced by air-cooled inflation forming of a propylene resin composition obtained by compounding 0.05-6.0 pts.wt. of a foaming agent to 100 pts.wt. of a polymer mixture comprising 10-100 wt.% propylene polymer (X) and 0-90 wt.% propylene polymer (Y) satisfying specific requirements (i) to (vi).
