Abstract: We conducted an extensive narrow-band survey (NB497; CW4977Å /BW77Å, which corresponds to Lyman-alpha wavelength at z = 3.06 ∼ 3.12) using the Suprime-Cam (Miyazaki, et al. 2002) 7FoVs (200Mpc×80Mpc) over the SSA22 proto-cluster regions, as well as in the general fields (SXDS 3FoVs, SDF, GOODS-N) at z = 3.1. We detected 260 Lyman-α absorbers (LAA), namely objects whose flux show significant deficit in the narrow band. We will discuss the spatial distribution and a very large overdensity of the LAAs by comparing them with those for the Lyman-α emitters (LAEs). In addition, we will compare the results of the Millennium Simulation with our observational results.
