Abstract: A compact container is the adjustment of a discharge amount of contents is easy. A compact container includes an inner container; an inner lid in which a communication hole is formed; a middle lid in which a discharge hole is formed; a first valve body; and a second valve body. When the inner pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space and the second valve body allows the discharge hole and the communication space to communicate with each other. When the inner pressure of the communication space is reduced by the operation portion, the second valve body blocks communication between the discharge hole and the communication space and the first valve body allows the communication hole and the communication space to communicate with each other.
