摘要： Provided is a foam discharger (200) including: a mixing portion (300) for mixing a liquid agent and a gas to foam the liquid agent; a discharge opening (242) for discharging the foamed liquid agent; and a flow path (250) in communication with the discharge opening, and for supplying the foamed liquid agent from the mixing portion to the discharge opening. The discharge opening is provided with a first porous member (270). On an upstream side of the first porous member, a cross-sectional area of the flow path on a cross section orthogonal to a supply direction in which the foamed liquid agent is to be supplied increases along the supply direction. The cross-sectional area of the flow path at the discharge opening is at least 1.2 times the minimum cross-sectional area of the flow path.
