Provided is a louver, which in particular has an elongated form, and to an air vent having at least one louver. The louver has a front region that takes up an entire longitudinal direction and a back region, wherein the front region and the back region are made of materials that differ in mechanical properties. The material of the front region preferably has a relatively high flexural stiffness in a longitudinal direction (x), whereas the material used for the back region has a flexural stiffness that is significantly lower than the flexural stiffness of the front region. The back region of the louver is longer than the front region in a transverse direction (y).
