Abstract: We present an initial result of a blind search for [CII] emitters at z∼ 4.5 using ALMA archival data. We used extra-galactic, band 7 data from eight Cycle 0 projects and searched for line emitters in the continuum-subtracted data cubes. However, we could not detect any new line emitters above a 6-σ significance level. This result provides upper limits to the z∼ 4.5 [CII] luminosity function down to L([CII])108 L (or SFR10 M yr-1). This work demonstated that we will be able to constrain the cosmic star-formation rate density by collecting archival data of Cycle 1 and 2 as the ALMA Patchy Deep Survey.
