In a fuel injection nozzle in which a throttle part is formed at the tip of the needle valve to loosely fit into the nozzle hole when seated, the nozzle hole is formed in a tapered hole shape whose diameter increases toward the fuel injection direction, while the throttle part has a tapered hole shape. A large diameter part on the distal end side having a slightly smaller diameter than the minimum diameter part of the nozzle hole and a small diameter part on the proximal end side having a smaller diameter than this large diameter part are formed, and the distal end surface of the large diameter part on the distal side is tapered. A throttle type fuel injection nozzle characterized by being formed into a shape.
