Abstract
The neutrino-less double beta decay is acquiring great interest
after the confirmation of neutrino oscillation
which demonstrated nonzero neutrino mass.
In order to search for neutrino-less double beta decay of $^{48}$Ca,
we proposed the CANDLES project by using CaF$_{2}$(pure) scintillators.
Now we installed the CANDLES III system at the Kamioka underground laboratory.
The CANDLES III system realizes the low background condition
by a characteristic structure and data analyses for background rejection.
Furthermore we installed new shielding system in order to reduce
$\gamma$-ray backgrounds from neutron capture reaction.
Here we report performances of the CANDLES III system.
