In a fuel injection device, a valve seat is formed on an inner peripheral surface of a valve body. The valve seat and a contacting portion of a needle form a sealing portion. Virtual perpendicular lines, which cross the sealing portion and are perpendicular to the inner peripheral surface of the valve body, intersect with each other at an intersecting point on a movable core side. The intersecting point is positioned between a first end of a guiding portion on a sealing portion side and a second end of the guiding portion opposite from the sealing portion. An end of the needle on a contacting portion side rotates around the intersecting point. Contact between the needle and the guiding portion is inhibited by positioning the intersecting point near the guiding portion.
