Abstract: A propylene polymer satisfying (a) below, a soft propylene copolymer satisfying (b) below, and a polyolefin containing a structural unit derived from an unsaturated carboxylic acid and/or a derivative thereof, wherein (a) a melting point is 100° C. or more, and (b) an MFR is in the range of 0.01 to 100 g/10 min, at least one of the following requirements (b-1) and (b-2) is satisfied: (b-1) a syndiotactic triad fraction s 60% or more, and (b-2) a structural unit derived from propylene is 55 to 90 mol % and a structural unit derived from at least one olefin having 2 to 20 carbon atoms (excluding propylene) is contained at 10 to 45 mol % (with provisos), and the relation between an intrinsic viscosity [η] (dL/g) and the MFR satisfies the relation: 1.50×MFR−0.20≤[η]≤2.65×MFR−0.20.
