The present invention provides a foam discharge container that is suitable for both prevention of dripping and stable discharge of foam in a preferable quality. This foam discharge container is provided with: a container body; a cap 2 to be attached to an opening of the container body; and a valve 3 for opening and closing a flow channel in the cap 2. The cap 2 has: a liquid material flow channel F1 that provides passage for a liquid material within the container body; an air flow channel F2 that provides passage for air within the container body; a mixing chamber F3 that is connected with these two types of flow channels F1, F2 while the valve 3 is in an open state; and a cap opening F4 that is connected with the outside of the container. The valve 3 comprises: a cylindrical fixed ring 32 which is fixed to the cap 2 at a position that surrounds the respective exits of the two types of flow channels; and an inner valve 34 which is formed inside the fixed ring 32 and which is elastically deformable and capable of simultaneously opening/closing the respective exits of the two types of flow channels F1, F2. The inner valve 34, in a closed state, is a membrane which is formed so as to lie from the cylindrical portion of the fixed ring 32 toward a central axis thereof and simultaneously to be slanted toward the container body side.
