The inveniton relates to a fuel injection valve of a direct injection engine. The fuel injection valve includes a valve body (841, 842) formed at a tip end thereof, with a nozzle hole (84) facing inside the cylinder, a cylindrical case (85) arranged inside the valve body and forming a fuel passage (800) by an inner circumferential surface of the case, a needle body (83) for opening and closing the nozzle hole (84), a movable core (871, 872) movably provided inside the case in along the cylinder axial direction and for driving the needle body (83) to open and close, and a solenoid coil (81, 82) arranged outside the case and for attracting the movable core (871, 872) by forming a magnetic circuit over the inside and outside of the case (85) when power is supplied to the solenoid coil, so that the valve body (83) opens the nozzle hole (84). A maximum fuel pressure inside the fuel passage (800) fuel injection valve is set to a high fuel pressure of 40 MPa or above, and the fuel injection valve (80) further includes a reinforcing member (891, 892) fitted externally onto the case (85).
