PROBLEM TO BE SOLVED: To solve such a problem that a plated layer runs over the inner periphery side of an axial hole.SOLUTION: A fuel injection valve 10 includes: a movable core 30 having an axial hole 34 and an axial end face 4032 on which a plated layer 360 is formed, and adapted to be moved to the side of a fixed core 20 with the operation of magnetically attractive force; and a valve member 40 having a shaft part 42 inserted into the axial hole 34 and a protruded part 44 capable of abutting on the axial end face 4032 of the movable core 30. The axial end face 4032 is formed with an inner periphery side end face part 4032a capable of abutting on the protruded part 44 and an outer periphery side end face part 4032b protruded from the outer periphery side thereof and capable of abutting on the fixed core 20. The movable core 30 has an annular recessed part 38 recessed in a range from an inner peripheral face 35 of the axial hole 34 throughout the periphery and opened to the axial end face 32. The plated layer 360 is formed on the inner periphery side end face part 4032a and set in the annular recessed part 38 without running over the inner periphery side of the axial hole 34. |
