  COMET (CO­her­ent Muon to Elec­tron Tran­si­tion) is an ex­per­i­men­tal pro­ject that hunts for a phe­nom­e­non of the con­ver­sion from the muon to the elec­tron (mu-e con­ver­sion). The mu-e con­ver­sion vi­o­lates the lep­ton fla­vor uni­ver­sal­ity and its dis­cov­ery in­di­cates a proof of the physics be­yond the stan­dard model of the par­ti­cle physics. The ex­per­i­ment uti­lizes a high-in­ten­sity pri­mary pro­ton-beam of J-PARC (Japan Pro­ton Ac­cel­er­a­tor Re­search Com­plex). The pro­ton beam is in­jected to a tar­get about 700mm long to gen­er­ate a high in­ten­sity muon beam so as to ac­cu­mu­late huge sta­tis­tics and achieve the final goal of a sen­si­tiv­ity of 10-16. Con­struc­tion of the ex­per­i­men­tal fa­cil­ity is un­der­way at a high pace to­wards an en­gi­neer­ing run in 2022 and the first physics run in 2023. In this pre­sen­ta­tion, we would like to pre­sent a cur­rent sta­tus of the COMET fa­cil­ity con­struc­tion.
