Beschreibung
Zusammenfassung:	A fuel injection valve equipped with: a holder (4) that accommodates a valve body (8), has a magnetic surface opposing the outer periphery of an armature (9), and is joined to a core (3); a housing (5) press-fitted onto the outer periphery of the holder (4) and housing a coil; and a cap (6) that covers the fuel-upstream side of the coil, and is press-fitted onto the outer periphery of the core (3). After the upper end surface of the housing (5) and the lower surface of the cap (6) are brought into contact in a state in which they are capable of sliding in the radial direction, the outer peripheral portions of the contact surfaces of the cap (6) and the housing (5) are joined by laser welding.
