We present the first measure of the evolution of type 1 and 2 active galactic nuclei (AGN1 and AGN2) in the mid-infrared (15 μm). We used a sample of 52 AGN selected from the southern ELAIS fields combined with a local sample of 91 AGN from the IRAS Faint Source Catalog. We find that AGN1 follow a luminosity dependent luminosity evolution with a rate kL=2.6, which stops at z larger than 2. A similar evolutionary scenario is found for AGN2 with kL=2.0-2.6, depending on the adopted k-correction. We estimate that AGN1 contribute about 3% to the cosmic mid-infrared background, while the AGN2 contribution is about 10%.
