Abstract: An object of the present invention is to provide a washer injector capable of injecting an amount of washer fluid which can properly wipe a windshield glass even when viscosity is increased or decreased depending on temperature change of the washer fluid. The washer injector includes a washer nozzle for injecting the washer fluid to the windshield glass of a vehicle, a washer pump for supplying the washer fluid to the washer nozzle, a fluid temperature sensor as a detection unit for detecting a fluid temperature which is a temperature of the washer fluid, and a control unit for controlling a discharge pressure of the washer pump. The control unit is configured to control the discharge pressure of the washer pump to be higher when the fluid temperature detected by the fluid temperature sensor is low than when the fluid temperature is high.
