To solve problems that, in a double aerosol vessel having a bottomed cylindrical case and a bag-like inner bag and capable of spraying the content in the inner bag outside the vessel by compressed gas sealed between the case and the inner bag, when the inner bag having a flange on its opening edge is used and the inner bag is inclined in the case, the flange cannot be sealed uniformly, and compressed gas or the content in the inner bag leak outside the vessel.

A foot part protruded from a bottom part of the inner bag to a bottom plate of the case is provided, and the dimension of protrusion of the foot part is substantially equal to a space between the bottom part and the bottom plate.
