To provide a sophisticated and inexpensive fuel injection valve achieving both improved sealability and workability of the closely-attached end surfaces of a plurality of body members.

A cylinder 14 storing a needle 1, a high-pressure fuel passage 31, and a low-pressure fuel passage 32 are formed in a nozzle body B2 having a nozzle port 12 formed in its tip, and a main body B1 is axially connected using a retaining nut B3 for connecting a high-pressure fuel passage 31 formed in the body members B1, B2. In an abutting portion, the peripheral edge portions of the body members B1, B2 are chamfered B21, B22 in order to form an annular seal groove S1. An annular seal member 7 formed of metal material softer than those of the body members B1, B2 is filled into the annular seal groove, and abutting end surfaces are subjected to a face seal S2 by the fastening force of the retaining nut B3, and at the same time, a peripheral seal portion S3 is formed by compressively deforming the seal member 7.
