An onboard sensor cleaning device includes a nozzle opening, a pump, a flow passage, an on-off valve, and a pressure accumulator. The nozzle opening ejects fluid to a sensing surface of an onboard sensor. The pump sends fluid to the nozzle opening. The flow passage connects the nozzle opening and the pump. The on-off valve is arranged in the flow passage to open and close the flow passage based on a control signal. The pressure accumulator is arranged in the flow passage in a pump-side portion that is a portion between the on-off valve and the pump.
