XMASS is a large volume multi-purpose experiment using a liquid xenon technology located underground in Kamioka Observatory, Japan. XMASS-I aims to search for dark matter, which is holding 832kg of liquid xenon in an active volume.
In this talk, the result of WIMPs search using fiducial volume analysis will be reported. The data accumulated between November 2013 and March 2016 were used for this analysis with 705.9days livetime. We present the WIMPs search with precise prediction of background events which are generated by radioactive decay in detector materials.
