Abstract: Provided is a less-expensive tube container that has excellent recyclability. This tube container 1 has an end seal part 30 that: is formed by welding an inner circumferential surface of a rolled sheet S that has been heated with hot air and then brought together in a first direction D1; and seals another end part 14 in the axial direction DA of a cylindrical body part 10. The sheet S includes a first base material layer SL1 that constitutes the inner circumferential surface of the sheet S when the sheet S has been rolled and a reinforcing layer RL that is further to the outer circumferential side than the first base material layer SL1. The first base material layer SL1 is formed from a not-stretched film that includes a polyester resin. The reinforcing layer RL is formed from a biaxially-stretched film that includes a resin component so as to be capable of supporting the first base material layer SL1 such that the inner peripheral surface as heated by hot air to become weldable is opposite itself in the first direction D1.
