A double container includes an outer layer body constituting an outer shell; an inner layer body including an upper opening communicating with a containing space, accommodated in the outer layer body, and deformable to undergo volume reduction; an inside plug including a tubular wall extending toward the containing space, a spherical body serving as a valve body being disposed inside the tubular wall; and a dispensing plug fitted to a mouth portion of the outer layer body and including a dispensing tube connected to the tubular wall. The tubular wall includes an inclined wall having a diameter decreasing toward the containing space and configured to abut against the spherical body over an entire circumference and including a protruding wall protruding from the inclined wall to the containing space. The protruding wall includes a liquid holding member holding a pool of liquid medium of the content formed below the spherical body.
