The fuel injector for fuel-injection systems of combustion engines has an excitable actuator for actuating a valve-closure member, which forms a sealing seat together with a valve-seat surface. At least one spray-discharge orifice is formed downstream from the valve-seat surface from which fuel is output in the direction of a combustion chamber. In addition, the fuel injector has a nozzle body, which surrounds the valve-seat surface or accommodates a valve-seat body having the valve-seat surface. The nozzle body is introduced into a downstream thin-walled extension of a connection piece, which also serves as an inner pole of a magnetic circuit, and is fixedly connected to this extension.
