Experimental search for the charged lepton flavor violation is a unique and powerful tool to investigate the physics beyond the standard model as a complementary way to high-energy frontier experiments. The COMET (COherent Muon to Electron Transition) experiment aims at searching for the mu-e conversion with a sensitivity better than 10000 times of the current experimental bound at 7x10-13 in two steps by using high-quality proton beam provided at J-PARC. We will present the current preparation status of the 1st stage of the experiment (COMET Phase I) and prospect of the 2nd stage (COMET Phase II).
