Plunger type high-pressure fuel pump

A plunger type high-pressure fuel pump is provided that can prevent variations of valve-closing operation resulting from a pressure difference caused between a hermetically closed space defined inside an electromagnetic valve of the fuel pump and an external space outside thereof. The electromagnetic valve includes: a valve member (91) including a suction valve (5); a solenoid coil adapted to displace the valve member; an anchor (32) made of a magnetic material provided with the valve member (91); and a core (30) forming a magnetic circuit to attract the anchor (32) by the electromagnetic force and dividing the inside of the electromagnetic valve into a hermetically closed space (38) and an external space (39) communicating with the fluid suction passage. The anchor (32) or the core (30) is provided with a fluid passage (41) through which fluid can flow between the hermetically closed space (38) and the external space (39) formed by the anchor (32) and the core (30), respectively when the suction valve (5) is in an opened state.
