The ATLAS Inner Detector uses three subdetectors for tracking of charged particles from r = 5 cm to r = 107 cm inside a solenoid magnet of 2 T. The innermost detector is a high resolution silicon pixel detector. It provides precise 3D tracking information close to the interaction point allowing secondary vertex reconstruction and hence b identification. It is followed by the SCT, a large area tracking device based on silicon strip detectors. The TRT, based on straw tubes, provides continuous tracking and improves electron identification due to its ability to detect transition radiation. These detectors are presently under construction. This report presents a brief report on the design, construction status and expected performance of the Inner Detector.
