A wiper blade (1) includes a blade rubber (2) and a rubber holder (3). In the rubber holder (3), a water channel (15) through which a washing liquid flows along a longitudinal direction is provided. In the rubber holder (3), an injection port (16) that communicates with the water channel (15) and is configured to be opened by water pressure and inject the washing liquid is provided. The injection port (16) is formed into a slit shape, and a plurality of injection ports are provided in the longitudinal direction. A width of the injection ports (16) varies along the longitudinal direction, and the injection port closer to an outer end side has a larger slit width. A larger amount of the washing liquid is injected from the injection port (16) having a larger slit width, and the injection amount of the washing liquid becomes larger toward the outer end side at which more washing liquid is required. |
