Zusammenfassung:	A container including a layer made of a resin composition containing: 57 to 75 mass% of propylene-based resin (A) which satisfies (a1) through (a4); 10 to 25 mass% of ethylene-based resin (B) which satisfies (b1) through (b3); and 10 to 18 mass% of propylene-based elastomer resin (C) which contains 50 mol% or more of constituent units derived from propylene and constituent units derived from α-olefins having 2, or 4 through 20 carbon atoms, and which satisfies (c1) through (c4) (assuming the total of (A) through (C) as being 100 mass%). (a1) MFR is 0.3 to 5.0 g/10 min. (a2) Ethylene content is 3.0 to 8.0 mass% (a3) Melting point is 135 to 150˚C (a4) Rockwell hardness is 65 to 90 (b1) MFR is 0.3 to 3.0 g/10 min. (b2) Density is 890 to 915 kg/m3 (b3) Molecular weight distribution is 3.5 or less (c1) Shore A hardness is 65 to 90 (c2) Melting point is 130 to 170˚C (c3) Density is 860 to 875 kg/m3 (c4) Glass transition temperature is -25 to -35˚C
