The Infrared Camera (IRC) is one of the of cal-plane instruments on board ASTRO-F (also called as the Infrared Imaging Surveyor; IRIS) and will make imaging and low-resolution spectroscopy observations over a wide spectral range in the near- to mid-infrared from 2 - 26 micron. The IRC will be operated in the pointed observation mode of ASTRO-F to make deep photometric and spectroscopic surveys of wide field-of-views. It will provide a significant database for studies of the formation and evolution of galaxies, properties of brown dwarfs, evolution of planetary systems, and processes of star of formation. The IRC comprises three channels: NIR (2 - 5 micron), MIR-S (5 - 12 micron) and MIR-L (12 - 26 micron), and employs state-of-the-art large format array detectors. The NIR channel uses a 512 x 412 InSb array and the MIR channels adopt 256 x 256 Si:As impurity band conduction (IBC) arrays. Each channel has a field-of-view of 10' x 10' with a nearly diffraction-limited spatial resolution. The NIR and MIR-S channels simultaneously observe the same field on the sky, while the MIR-L observes the sky about 20' away from the NIR/MIR-S position. The design overview and current development status of the IRC are presented.
