Abstract: An object of the present invention is to reduce the pressure loss in a relief valve employed for a high-pressure liquid supply pump. Disclosed is a high-pressure liquid supply pump for pressurizing a liquid and supplying the pressurized liquid from a low-pressure side to a high-pressure side. The pump includes a relief path which releases the pressurized liquid from the high-pressure side to the low-pressure side, and a relief valve which is positioned in the relief path and equipped with an intermediate chamber, a valve seat positioned toward the high-pressure side of the intermediate chamber, a ball valve that is attachable to and detachable from the valve seat, and a ball valve retainer for pressing the ball valve against the valve seat. The relief path is configured so that an inflow path to the intermediate chamber and an outflow path from the intermediate chamber both produce a restriction effect. The ball valve retainer has a pressure reception surface for receiving the pressure from the intermediate chamber. A first pressure reception area, which detaches the ball valve from the valve seat upon receipt of liquid pressure of the pressurized liquid from a high-pressure section when the relief valve closes, is smaller than a second pressure reception area, which lifts the ball valve and the ball valve retainer upon receipt of liquid pressure from the intermediate chamber.
