To provide a fuel injection valve for an internal combustion engine, having high durability.
The fuel injection valve 10 includes: a cylindrical inlet member 13 having an inlet fitting portion 130 on an opposite side from fuel piping 2 in an axial direction, in which pressing axial force N acts toward a support face portion 1d side by the pressure of supplied fuel from the fuel piping 2 and the supplied fuel flows to an inner peripheral side in a radial direction; and a cylindrical reception member 12 having a reception fitting portion 120, which is welded to the inlet fitting portion 130 coaxially fitted from a fuel piping 2 side, supported in the axial direction by a support face portion 1d and containing a valve member 40 on the inner peripheral side in the radial direction. The end face 122 of the reception fitting portion 120 axially contacts with a projection 132 projecting in the radial direction more than the inlet fitting portion 130. The reception fitting portion 120 and the inlet fitting portion 130 are welded in the radial direction at a part axially separated from a contact interface 70 between the end face 122 and the projection 132.
