PROBLEM TO BE SOLVED: To provide a paper cut free from any leakage caused by pin holes or non-sealed portions, and capable of breaking a paper layer of the container when peeling a heat-sealed lid, and obtaining easy-unsealability without impairing its sealing strength. SOLUTION: In the paper cup P consisting of a cylindrical cup barrel member W and a bottom member to seal a bottom portion of the cylindrical cup barrel member W, an innermost layer 6a of the barrel member W consists of a low-density polyethylene resin layer having a density of 0.90-0.93 g/cm<SP>3</SP>, and the bottom member F consists of a straight-chain type low-density polyethylene resin layer which is polymerized by using a metallocene-based single site catalyst.
