  We present continuum images of the "Galactic Center Mini-spiral" of 100, 250,
and 340 GHz bands with the analysis of the Cy.0 data acquired from the Atacama
Large Millimeter/submillimeter Array (ALMA) archive. Pretty good UV coverage of
the data and the "self-calibration" method give us an opportunity to obtain
dynamic ranges of over 2x10^4 in the resultant maps of the 250 and 340 GHz
bands. In particular the image of the 340 GHz band has high dynamic ranges
unprecedented in sub-millimeter wave. The angular resolutions attain to
1.57"x1.33" in the 100 GHz band, 0.63"x0.53" in the 250 GHz band, and
0.44"x0.38" in the 340 GHz band, respectively. The continuum images clearly
depict the "Mini-spiral", which is an ionized gas stream in the vicinity of Sgr
A*. We found the tight correlation between the dust emission peaks and the
OB/WR stars in the Northern-arm of the "Mini-spiral". The core mass function of
the dust core identified by the clumpfind algorithm would obey the flat
power-law dN/dM=aM^-1.5+/-0.4 on the high-mass side. These support the scenario
that the star forming cloud has fallen into the immediate vicinity of Sgr A*
for the origin of the Central cluster.
