The invention relates to a windscreen wiper comprising a wiper arm (10) which is driven by a drive shaft and to which a wiper blade (20) is hinged. At least one jet nozzle (64) is mounted on a pivoting part (10, 22) and is connected to a water pump via a water inlet (56). The invention provides for a nozzle body (40) having an inlet port (42) and at least one outlet port (44) to be situated in a housing (36). The inlet port (42) starts at a face (52) pointing towards the water inlet (56) and discharges on a lateral surface (54) of the nozzle body (40), while the outlet port (44) starts at the lateral surface (54) at a distance from the inlet port (42) and discharges into a jet port (46) leading to a spray nozzle (64). In the unpressurized state a membrane (58, 70) closes the inlet port (42) and the outlet port (44).
