Based on a deep multi-wavelength catalog in the Subaru XMM-Newton Deep Survey Field (SXDS), covering a wide wavelength range from the $u$-band to the IRAC $8.0\\mu m$ over 0.7 deg$^2$, we evaluate photometric redshift to identify massive ($M_{\\star}\\sim10^{11}\\ M_\\odot$) galaxies with suppressed star formation.
