We have performed soft x-ray and ultrahigh-resolution laser-excited 
photoemission measurements on tetragonal FeSe, which was recently identified as 
a superconductor. Energy dependent study of valence band is compared to band 
structure calculations and yields a reasonable assignment of partial densities 
of states. However, the sharp peak near the Fermi level slightly deviates from 
the calculated energy position, giving rise to the necessity of self-energy 
correction. We have also performed ultrahigh-resolution laser photoemission 
experiment on FeSe and observed the suppression of intensity around the Fermi 
level upon cooling.
