  AKARI/IRC has a capability of the slit-less spectroscopy in the mid-infrared
(5--13 $\mu$m) over a 10 arcmin$\times$10 arcmin area with a spectral
resolution of 50, which is suitable for serendipitous surveys. The data
reduction is, however, rather complicated by the confusion of nearby sources
after dispersing the spectra. To make efficient and reliable data reduction, we
first compiled a point-source list from the reference image in each
field-of-view and checked the overlaps of the spectra using their relative
positions and fluxes. Applying this procedure to 886 mid-infrared slit-less
spectroscopic data taken in the cryogenic phase, we obtained 862 mid-infrared
spectra from 604 individual non-overlapping sources brighter than 1.5 mJy. We
find a variety of objects in the spectroscopic catalogue, ranging from stars to
galaxies. We also obtained a by-product catalogue of 9 $\mu$m point sources
containing 42,387 objects brighter than 0.3 mJy. The spectroscopic and
point-source catalogues are available online.
