   An obscaured nulceus in Seyfert 2 galaxies have been revealed. It is
   predicted by the unified scheme of Seyfert galaxies. Although the
   nature of some seyfert 2 galaxies are well described by the model, a
   question is still remaining. It is whether the model can apply for
   all of Seyfert 2 galaxies. We select unbiased sample with the
   intensity of the forbidden line, [OIII]5007, which associates with
   AGN activity. We will check the existence of obscured nuclei. Bright
   [OIII] sample may have an bright nucleus. Our observation will
   resolve the open question why there are few bright Seyfert 2
   galaxies.
