Abstract: A valve seat has an inner passage and outer passages. A suction valve member has first passages and a first projection portion that guides, to the first passages, the fuel that flows from a pressure chamber at the time of valve opening.

Fuel flows through a passage radially outside the suction valve member and the first passages. A fluid passage area is securable even when a lift amount of the suction valve member is small.
