Using a narrow-band filter centered at 2.033µm, [O III] λ5007 emitters at z∼3.06±0.02 were searched to examine star-forming activities in an over-density region where a clustering of Lyman Break Galaxies (LBGs) and Lyman α emitter candidates around z=3.09 was reported, though the targeted redshift is slightly different from that of the peak of the over-density region. Although one emitter candidate at z=3.06 was detected, it is likely to be located at a redshift of between 1 and 2 judged based on multi-band photometry. Another emission-line object was detected in another narrow-band filter (``off band'' filter) centered at 2.120µm, which is identified with a galaxy at z=0.132 (the emission line is Paschen α). The K'-band imaging data revealed the presence of 12 Extremely Red Objects (EROs) with I814-K'≥4. The distribution of the EROs does not seem to coincide with that of Lyman Break Galaxies or Lyman α emitters at z∼3. The magnitudes and colors of the EROs are not consistent with those of passively evolving massive elliptical galaxies at z∼3. Candidates for counterparts of the submm sources detected with SCUBA are found; no EROs around the submm sources are found in our magnitude limit. File Summary:

Note (1): We adopt the ``BEST'' magnitudes determined by SExtractor as the total magnitudes in each band for the K', N204 and N212 magnitudes. Note (2): U'AB and VAB magnitudes from Lilly et al. (1991ApJ...369...79L). B and I magnitudes from Cowie et al. (1996AJ....112..839C). For I and B magnitudes, for objects which are not reported in Cowie et al. (1996AJ....112..839C) but appear in Lilly et al. (1991ApJ...369...79L) with significances of more than 3σ, B{AB} and I{AB} in Lilly et al. (1991ApJ...369...79L) are converted to B and I by using B=B{AB}+0.17 and I=I{AB}-0.48 (e.g., Lilly et al., 1991ApJ...369...79L), respectively.
