PROBLEM TO BE SOLVED: To provide a paper cup excellent in light shielding properties and excellent in sealing performance in which contents are prevented from leaking due to omission of a seal. SOLUTION: A body member using a body member laminate 10 including at least a paper base material 11, an aluminum foil 15 layer and an innermost layer, and a bottom member layering including at least a paper base material, an innermost layer and an outermost layer. In the paper cup which consists of the bottom member using the body 20, the innermost layer of the body member laminate, the bottom member laminate, and the outermost layer of the bottom member laminate are polymerized using a single site catalyst. This is a resin layer containing the copolymer 21. According to the configuration, the paper cup is excellent in light-shielding properties and excellent in sealing properties in which contents are prevented from leaking due to missing seals.
