We constructed a spectral catalog of diffuse radiation of the sky obtained by the InfraRed Camera (IRC) onboard AKARI. There is no precedent for spectral catalogs of the infrared diffuse radiation, thus this is the first infrared spectral catalog of the diffuse radiation in the world. This catalog contains the 278 low-resolution ( λ/Δλ- 20) near-infrared (1.8-5.3 μm) spectra of diffuse sky covering a wide range of galactic and ecliptic latitudes before the exhaustion of liquid-helium. Advanced reduction methods specialized for the slit spectroscopy of diffuse sky spectra have been developed for constructing the spectral catalog. Point sources brighter than mK (Vega)=19 were detected on the slit and masked for deriving the diffuse spectrum, and the brightness due to unresolved Galactic stars under this detection limit is negligible. Using this catalog, the diffuse radiation was successfully separated into three components of the zodiacal light (ZL), the diffuse Galactic light (DGL), and the extragalactic background light (EBL). In this paper, the specialized reduction methods for AKARI infrared diffuse radiation, and the method of component separation of the near-infrared diffuse spectrum are described.
