A fuel injection valve includes a nozzle body including an injection aperture; a needle that is slidably located in the nozzle body, forms a fuel introduction path between the needle and the nozzle body, and is seated on a seat portion in the nozzle body; a swirling flow generating portion that is located more upstream than the seat portion, and imparts a swirl with respect to a sliding direction of the needle to fuel introduced from the fuel introduction path; a swirl velocity increasing portion that is located more downstream than the seat portion, and increases a swirl velocity of a swirling flow generated in the swirling flow generating portion; and an air bubble reserving portion that is located more downstream than the swirl velocity increasing portion, and reserves air bubbles generated by passage through the swirl velocity increasing portion. The injection aperture opens in the air bubble reserving portion.
