PROBLEM TO BE SOLVED: To provide an injector at low manufacturing cost. SOLUTION: This injector comprises a body, a sheet 25 fixed to a tip of the body, and a valve having a ball on its tip and an armature on its rear end, and reciprocated and slid in the body. Plural continuous projection parts are formed on the sheet 25 in parallel with the sliding direction of the valve, and projecting tip parts 25h are pressurized and deformed by casting work to form a slide face 25j. The slide face 25j formed by casting the tip parts 25h are manufactured with high accuracy in size, and the cost can be reduced by applying the casting work.
