Abstract
We present the 2.12$\mu$m narrow-band image of the Hubble Deep Field North taken with the near-infrared camera (CISCO) on the Subaru telescope. Among five targets whose H$\alpha$ or [O{\sc iii}] emission lines are redshifted into our narrow-band range expected from their spectroscopic redshift, four of them have strong emission lines especially for the two [O{\sc iii}] emission-line objects. The remaining one target shows no H$\alpha$ emission in spite of its bright rest-UV luminosity, indicating that this object is already under the post-starburst phase. The volume-averaged SFR derived from the detected two H$\alpha$ emission is roughly consistent with that evaluated from the rest-UV continuum.
