The discharging portion includes a foam passing chamber that allows the foam body to pass, and one or a plurality of ejection-port forming wall portions that extend downward below the foam passing chamber, are formed into a closed-loop shape in plan view, have the inner space communicating with the foam passing chamber, and have the lower edge having an ejection port formed thereon. At least part of the ejection-port forming wall portion has a bottom end portion formed into a shape that has a thickness reduced toward the lower side. The ejection-port forming wall portion and a second portion. The height position of a lower edge of the first portion is higher than the height position of a lower edge of the second portion.
