The present invention addresses the problem of providing a fuel injection pump with which white smoke in exhaust gas can be significantly reduced. In this fuel injection pump (100) which delivers, at high pressure, fuel to be injected into a combustion chamber of a diesel engine, a delivery valve (10) is provided to a midpoint of a route along which the fuel is pumped from a plunger (104) to a fuel injection nozzle. A damping valve (17) is provided to a downstream side of the delivery valve (10). The damping valve (17) is provided with: a valve body (15) which has an orifice (15a) formed in an axial-centre part thereof, and which is impelled downwards (towards an upstream side) by a damping-valve spring (18); and a receiving body (16) which has a passage hole (16a) formed in an axial-centre part thereof, and which comes into contact with the valve body (15). A recess (15b) which communicates with the passage hole (16a) is formed in a receiving-body (16) facing surface of the valve body (15).
