In order to provide a fuel-supply pump which can be produced at reduced cost and which exhibits increased durability, this fuel-supply pump 1 is provided with a suction valve 30 and a suction valve stopper 32. The suction valve stopper 32 restricts the movement of the suction valve 30 in a valve-opening direction (in a direction in which the suction valve 30 separates from a seat member 31). The suction valve stopper 32 has a disc-like part 32d and a plurality of plate-like parts 32m. The disc-like part 32d has a protrusion 32b that faces the suction valve 30. The plurality of plate-like parts32m support the disc-like part 32d. 本发明提供一种能在抑制制造成本的情况下提高耐久性的燃料供给泵。为此，本发明的燃料供给泵(1)具备吸入阀(30)和吸入阀止动件(32)。吸入阀止动件(32)限制吸入阀(30)的开阀方向(吸入阀(30)离开阀座构件(31)的方向)的移动。吸入阀止动件(32)具有圆盘状部(32d)和多个板状部(32m)。圆盘状部(32d)具有与吸入阀(30)相对的凸部(32b)。多个板状部(32m)支撑圆盘状部(32d)。
