A fuel control valve includes a case and a movable body that is movably housed in the case. The case has a valve seat surface shaped in an inner cone shape whose inner diameter increases toward a tip. A valve element surface is operable by the movable body, and is in contact with the valve seat surface along a seal line in a valve closed state. The valve element surface is separated from the valve seat surface in a valve open state. Plural grooves are disposed between the tip and the seal line to expand radially outside from the valve seat surface. Plural projections are defined between the grooves to intermittently leave the valve seat surface.
