To provide a vessel which enables washing of rice by only a tap water stream and hydraulic pressure without touching water, the rice and the vessel.

A vessel is shaped like a laterally-elnogated letter-V, and thereby rice is washed at the bottom of the V-shaped vessel and both of the right and left end parts thereof. By providing a draining portion in the central upper part of the vessel, the water after washing, separated from the rice is drained without causing any clogging.
