WASHING MACHINE

A washing machine is provided with a detergent case (400) in which a first housing chamber (410) for housing a detergent therein is formed, and a flow channel structure part which forms a flow channel on the detergent case (400). In the flow channel structure part, a plurality of falling holes which direct water in the flow channel toward the detergent case (400) are formed. The detergent case (400) includes a partition wall (414) which partitions the first housing chamber (410) into a mixing chamber (412) in which a water solution of the detergent is produced by mixing the detergent and the water, and a foaming chamber (413) in which the water solution flowing therein from the mixing chamber (412) is foamed. The plurality of falling holes include a first falling hole which directs the water to the mixing chamber (412), and a second falling hole which directs the water to the foaming chamber (413).
