Fuel injection valve

A fuel injection valve comprising:

• a fixed core configured to form a part of a magnetic circuit that is to cause a magnetic flux to flow therethrough;
• a movable core configured to form a part of the magnetic circuit and configured to be driven by a magnetic attraction force generated in a gap between the movable core and the fixed core;
• a valve body configured to perform a valve opening operation caused by driving the movable core to open a nozzle hole to inject fuel;
• a yoke configured to form a part of the magnetic circuit and accommodating the fixed core;
• a coil placed in a coil chamber between the fixed core and the yoke and configured to generate the magnetic flux on energization;
• and
• a filling resin member with which the coil chamber is filled and having an electrical insulation property, wherein
• the fixed core includes:
• a cylindrical main body portion that has a core facing surface facing the movable core;
• and
• a protruding portion that protrudes radially outward from an outer peripheral surface of the cylindrical main body portion and is in contact with the yoke to cause the magnetic flux to pass therethrough,
• the protruding portion defines a resin molding flow channel to cause molten resin serving as the filling resin member to flow into the coil chamber, and
• a length of the protruding portion in a direction of a cylinder center line of the fixed core is set to be shorter toward a radially outer side of the fixed core.
