To provide a back door capable of suppressing deformation of an outer panel even when an inner panel is joined to the outer panel.SOLUTION: A back door 1 includes an inner panel 4, an outer panel 5 that has a linear expansion coefficient K2 different from a linear expansion coefficient K1 of the inner panel 4 and is provided with an opening part 5a, and an annular waterproof member 6 that is provided between the inner panel 4 and the outer panel 5 to surround the periphery of the opening part 5a. The annular waterproof member 6 includes a lower side section in a gravity direction with respect to the opening part 5a, which is composed of an adhesive 6a, and an upper side section, which is composed of a sponge seal member 6b including an adhesive and a sponge. The outer panel 5 has a drain port 5b located below the opening part 5a in a region surrounded with the annular waterproof member 6.SELECTED DRAWING: Figure 2
