PROBLEM TO BE SOLVED: To provide a double container having an outer container and an inner container connected to each other, which can prevent their buckling at a manufacturing step of the outer container and a hindrance caused by vertical arrangements of two curled portions can be avoided. SOLUTION: This double container 1 comprises an outer container 10 having an easily opened part 14 extending along the circumference of a barrel part 11, and an inner container 20 having a curled part 23 rounded outward at the upper end of a barrel 21 and arranged on the inside of the outer container 10, wherein the outer container 10 and the inner container 20 are connected to each other to form a closed space 15 below the inner container 20 by the outer container 10 and the inner container 20. The outer container 10 has a single end 13 obtained by cutting the single walled upper end of the barrel 11, and then the single walled end 13 and the curled part 23 of the inner container 20 are adjacent to each other.
