Deep narrow- and broad-band near-infrared imaging observations of the central 2 ' x 2 ' region of the SSA 22 field were made with the near-infrared camera (CISCO) attached to the Subaru Telescope. Using a narrow-band filter centered at 2.033 mum, [O iii] lambda 5007 emitters at z similar to 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 ce 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 or between 1 and 2 judged based on multi-band photometry. Another emission-line object was detected in another narrowband filter ("off band" filter) centered at 2.120 mum, which is identified with a galaxy at z = 0.132 (the emission line is Paschen alpha). The K ' -band imaging data revealed the presence of 12 Extremely Red Objects (EROS) with I-814 - K ' greater than or equal to 4. The distribution of the EROs does not seem to coincide with that of Lyman Break Galaxies or Lyman a emitters at z similar to 3. The magnitudes and colors of the EROS are not consistent with those of passively evolving massive elliptical galaxies at z similar to 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.
