A vane pump 100 is provided with: a high-pressure chamber 12 formed in a groove shape in a bottom part of a pump-accommodating concavity 10a, a working fluid being guided to the high-pressure chamber 12 through a first discharge port 9a and a second discharge port 9b; and a high-pressure passage 19 having an opening 19a that opens into the high-pressure chamber 12, the high-pressure passage 19 guiding working oil out of the high-pressure chamber 12. The first discharge port 9a or the second discharge port 9b is disposed so as to face the opening 19a of the high-pressure passage 19, and the flow channel cross-sectional area of the high-pressure chamber 12 is less than the total flow channel cross-sectional area of the first discharge port 9a and the second discharge port 9b.
