Abstract: A fluid injection valve (1) is disclosed. It comprises a valve assembly (100) with a tubular valve body (110) and a valve needle (140) and an electromagnetic actuator assembly (200) with a moveable core (210). The tubular valve body (110) comprises a one-pieced upper part with a pole portion positioned axially subsequent to the moveable core (210) in direction towards the fluid inlet end (3), and with a connection portion (124) axially projects beyond the moveable core (210) in direction towards the fluid outlet end (5). The tubular valve body (110) comprises a one-pieced lower part (130) in which the valve needle (140) is received. The valve needle (140) and/or the valve body (110) comprise first (160) and second (170) guide elements for axially guiding the valve needle (140) with respect to the lower part (130) of the valve body (110).
