  An experiment to search for hypothetical particle dark matter using cryogenic
thermal detector, or bolometer is ongoing. The bolometer consists of eight
pieces of 21 g LiF absorbers and sensitive NTD germanium thermistors attached
to them and is installed in the Nokogiriyama underground cell which is a
shallow depth site ($\sim 15$ m w.e.). We report on the results from the first
running for about ten days using this arrayed bolometer system together with
appropriate shieldings and muon veto counters. From the obtained energy spectra
the exclusion limits for the cross section of the elastic neutralino-proton
scattering are derived under commonly accepted astrophysical assumptions. The
sensitivity for the light neutralino with a mass below 5 GeV is improved by
this work.
