PROBLEM TO BE SOLVED: To obtain a washer nozzle capable of preventing a function of a check valve from decreasing. SOLUTION: In the washer nozzle 10, when a cleaning liquid is fed into a communicating hole 40 from a feeding hole 36 through a feeding passage 34, the communicating hole 40 is opened by a valve element 84 of a valve seat 78 by a flow pressure of the cleaning liquid. Therefore, the cleaning liquid is made to flow into a communicating passage 62, and furthermore, it is sprayed from a spraying hole 72 through a flow path of the valve seat 78, a guiding passage 70 and a spraying passage 68. In addition, as a filter part 44 in an inserting hole 38 prevents foreign substances in the cleaning liquid 16 from passing through, the spraying hole 72 can be prevented from clogging. In this case, the filter part 44 is provided on the feeding hole 36 side closer than the valve seat 78 in a water passage 74. It is possible thereby to prevent the movement of the valve seat 78 from being obstructed and closure properties of the valve seat 78 from being deteriorated by the foreign substances in the cleaning liquid 16 blocked by the filter part 44 so that the function of the valve seat 78 is prevented from being lowered.
