PROBLEM TO BE SOLVED: To provide a cup-shaped container made from a laminated material mainly of paper in which a synthetic resin can be fixed to a cup-shaped container without breaking a barrier layer and which does not affect the taste of the contents. SOLUTION: A synthetic resin opening fringe member 4 made by an insert molding method in which an container main body 2 is inserted into a molding mold, and a resin is injected is installed integrally on the periphery of the opening of the container main body 2 having a barrel part and a bottom part which are formed from a composite material mainly of paper. The composite material is made from a laminated material having a barrier layer, the synthetic resin outermost layer, and the innermost layer and is a composite container 0.2-1.0W/m.k, preferably 0.4-0.7W/m.k in thermal conductivity. |
