Beschreibung
Zusammenfassung:	An object of the present invention is to provide a high-pressure fuel supply pump having a structure capable of adjusting the moving speed of an anchor. Therefore, the high-pressure fuel supply pump of the present invention is provided with a protrusion that protrudes toward an anchor side on a fixed core facing surface of a fixed core. The protrusion is configured in such a manner that a minimum distance between the protrusion and an anchor facing surface is smaller than an axial gap dimension configured between the fixed core facing surface and the anchor facing surface in a direction along a central axis in a state where the anchor is stationary at the time of non-energization.
