PROBLEM TO BE SOLVED: To provide a fuel injection valve reducing magnetic resistance of a section where non-magnetic pipe covering at least part of an outer circumference surface of at least one of a movable core and a fixed core abuts on a yoke and suppressing drop of stiffness of the non-magnetic pipe. SOLUTION: A pipe member 12 of a fuel injection valve 10 includes a magnetic pipe 16 and the non-magnetic pipe 16 in this order from a side of an injection hole plate 20 having an injection hole formed thereon. The non-magnetic pipe 16 includes a thin wall part 17 formed by denting an outer circumference surface to an inside. Thickness t of the thin wall part 17 is set in a range of 0.2 mm≤t≤1.0 mm. The yoke 54 covers an outer circumference of a coil 50. An abutment part 55 of the yoke 54 abuts on the magnetic pipe 14 in radial direction outside of the movable core 30, and an abutment part 56 of the yoke 54 abuts on the thin wall part 17 of the non-magnetic pipe 16 in radial direction outside of the fixed core 34.
