A fuel injection pump delivers, at high pressure, a fuel to be injected into a combustion chamber of a diesel engine and includes a delivery valve disposed in the middle of a path for pressure-feeding the fuel from a plunger to a fuel injection nozzle. A damping valve is disposed on the downstream side of the delivery valve. The damping valve includes a valve element which has an orifice formed on an axial part thereof and is biased downward (toward the upstream side) by a damping valve spring and a receiving element which has a passage hole formed on an axial part thereof and abuts against the valve element. A recess which communicates with the passage hole is formed on a face of the valve element, the face facing the receiving element.
