A fuel injection valve has a nozzle body that accommodates a nozzle needle, in which at least one fuel supply line is introduced into the nozzle body; a nozzle holder, in which at least one fuel supply line is introduced into the nozzle holder, the at least one fuel supply line being in communication with a respective fuel supply line of the nozzle body; and a clamping nut that axially clamps the nozzle body and the nozzle holder together. A coolant supply line and a coolant discharge line communicating with each other are introduced into the nozzle body and the nozzle holder. On the end face of the nozzle body and/or on the end face of the nozzle holder adjoining the end face of the nozzle body, an outer sealing surface and at least one inner sealing surface separated from the outer sealing surface by at least one recess are formed, the respective inner sealing surface sealing the respective communicating fuel supply line in the region of the adjoining end faces, the respective outer sealing surfaces seal th
