抄録（英）
We study infrared properties of star-forming (SF) galaxies selected by 250 micrometers band detection of the Herschel/SPIRE survey on the entire North Ecliptic Pole (NEP) field of AKARI. We matched SPIRE sources with the spectroscopic survey data and combined with those in the AKARI NEP-Wide catalogue covering from optical to 24 micrometers band. We selected around 250 star-forming galaxies and carried out spectral energy distribution (SED) fit analysis to derive physical quantities. Our SED-fit is based on the continuous near- to mid-IR coverage by 9 photometric bands as well as reliable constraint on far-IR peak by Herschel. Our sample galaxies have prominent mid-IR PAH features and majority of them are LIRG type population in the low-z (less than 0.9). Although they do not seem to form a tight concentration along the galaxy main-sequence due to a wide range of redshift (z is greater than 0.0 and less than 0.9) and various morphological types, they show the downsizing evolutionary pattern toward the present epoch.
