FOAM DISCHARGER

PROBLEM TO BE SOLVED: To provide a foam discharger which smoothly excludes water intruded in an air chamber to avoid a state that the water is left accumulated in the air chamber. SOLUTION: The foam discharger 10 opens a first flow passage 32 and a second flow passage 33 which send out content liquid from a pressurized liquid chamber 30 and the air chamber 24 by pressing a pump head part 19 provided in a base cap part 14, mixes the sent content liquid with the air in a mixing chamber 13, and makes a foam generation member 20 foam on a foaming flow passage 21 to discharge the content liquid, wherein the bottom 24a of the air chamber 24 becomes an inclined surface which inclines downward toward a liquid introduction chamber 28, and a fine drain hole 50 which makes a container body 11 exclude the water accumulated inside by pressurization when the pump head part 19 is pressed is provided at a part approximate to the air chamber 24 of the liquid introduction chamber 28 in which an adhesion sliding part 15a of a cylindrical piston member 15 is arranged at a state that the pump head part 19 is not pressed.
