The ATLAS Pixel Detector is the innermost layer of the ATLAS tracking system and will contribute significantly to the ATLAS track and vertex reconstruction. The detector consists of identical modules, arranged in three barrel layers concentric with the beam line and centered on the interaction point and three disks on either side for the forward region. The position of the Pixel Detector near the interaction point requires excellent radiation hardness, mechanical and thermal robustness, and good long-term stability, all combined with a low material budget. The detector layout results from production modules and the status of assembly are presented.
