To provide a laminated structure of a barrier sheet piece capable of consistently and reliably exhibiting barrier performance on a head of an aluminum laminate tube container.
In the aluminum laminate tube container, a head with a mouth cylindrical part erected from an upper end opening of a shade-like shoulder is hot-melt and fixed to an upper end of a barrel formed of an aluminum laminate sheet in a cylindrical shape, the head has a head resin part forming a base material, and a ring-like barrier sheet piece formed of the aluminum laminate sheet to be hot-melt and laminated on an area from an upper end to a lower end of at least an outer peripheral surface of the shoulder of the head resin part. An upper end of the barrel is hot-melt and layered on a lower end of the head resin part in a housing manner, and a lower end face on the barrier sheet piece and an upper end face of the barrel are abutted on and joined with each other on the outer peripheral surface of the head resin part so as to be hot-melt and lined by the head resin part from the inside.
