a second wall being bent and extending from one end of the first wall; and

a third wall being bent and extending from the other end of the first wall to face the second wall,

wherein the branch flow path branches from the flow path to face the second wall of the water supply plate, and

wherein the water supply nozzle is arranged on the first wall of the water supply plate in such a way that the water supply hole faces the third wall of the water supply plate.

10. The washing machine of claim 9, wherein a drain hole configured to discharge washing water flowing into the branch flow path is formed on the branch flow path,

wherein the drain hole is formed in a corner portion of the water supply plate formed by the first wall and the second wall.

11. The washing machine of claim 1, wherein the water supply plate further comprises a first rib and a second rib provided to define the flow path,

wherein the water supply nozzle comprises a water supply hole provided to face the second rib to supply washing water to the flow path, and

wherein a drain aperture configured to discharge washing water leaking from the flow path is formed on the outside of the second rib.

12. The washing machine of claim 11, wherein the drain aperture is formed on the outside of the second rib so as to be arranged between the water supply nozzle and the at least one flow path partition.

13. The washing machine of claim 1, wherein the detergent box further comprises an additional accommodating portion in which detergent is placed,

wherein the water supply plate further comprises:
