Abstract: PURPOSE:To reduce the elution of an org. substance, by forming a plasma polymerization layer to the inside surface of each of the piping between apparatuses and the piping up to an area using ultrapure water. CONSTITUTION:Primary pure water Wa supplied is subjected to sterilization treatment due to the irradiation of ultraviolet rays in an ultraviolet sterilizing apparatus 1 and introduced into an ion exchange apparatus 2 through piping 4A to remove the dissolved ion in the primary pure water Wa. The primary pure water Wa after the removal of the ion is introduced into an ultrafiltration apparatus 3 through piping 4B and fine particles contained in the primary pure water Wa are removed to obtain ultrapure water Wb which is, in turn, supplied to a use area through piping 4C. A plasma polymerization layer 6 comprising a monomer such as hydrocarbon, a nitrogen-containing compound and a fluorine- containing compound is formed to the piping main body of each of the pipings 4A-4C. By this method, ultrapure water is obtained.
