N2 - We present basic properties of 3300 emission line galaxies detected by the FastSound survey, which aremostly H emitters at z 1.2-1.5 in the total area of about 20 deg2, with the H flux sensitivity limit of 1.6 1016 erg cm2 s1 at 4.5 . This paper presents the catalog of the FastSound emission lines and galaxies, which is open to the public.We also present basic properties of typical FastSound H emitters, which have H luminosities of 1041.8-1043.3 erg s1, star formation rates (SFRs) of 20-500M yr1, and stellar masses of 1010.0-1011.3M. The 3D distribution maps for the four fields of Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) W1-4 are presented, clearly showing large scale clustering of galaxies at the scale of 100-600 comoving Mpc. Based on 1105 galaxies with detections of multiple emission lines, we estimate that the contamination of non-H lines is about 4% in the single-line emission galaxies, which is mostly [O III]5007. This contamination fraction is also confirmed by the stacked spectrum of all the FastSound spectra, in which H, [NII]6548,6583, [S II]6717,6731, and [OI]6300,6364 are seen.
