To provide a bubble generator that can suppress evaporation of an alcohol component of a washer fluid and turn the washer fluid into a rotational flow by a simple constitution.SOLUTION: A supply part 6 integrated with a bubble generator includes an air bubble part that makes air bubbles included in a washer fluid W supplied to an object of a vehicle, and a rotational flow generation part that is provided on the upstream side of the air bubble part and that generates a rotational flow in the washer fluid W. The rotational flow generation part comprises a flow straightening blade 63 for straightening a flow of the washer fluid W, and a swirler 73 for generating a rotational flow in the washer fluid W straightened by the flow straightening blade 63.SELECTED DRAWING: Figure 3
