PROBLEM TO BE SOLVED: To provide a highly pure container for pretreatments of elemental analyses, which is used for the pretreatments of the elemental analyses and has superior heat resistance and chemical resistance such as acid resistance or the like; to provide an inductively-coupled plasma torch with superior durability which is of inductively-coupled plasma torches used for an analysis system adopting an ICP method and makes it possible to carry out precise elemental analyses; and to provide an elemental analysis system which has the plasma torch and uses the ICP method. SOLUTION: The container for the pretreatments of the elemental analyses, which is used for the pretreatments of the elemental analyses, is a ceramic container manufactured by a chemical vapor deposition (CVD) method. Furthermore, the inductively-coupled plasma torch which is used for the elemental analysis system adopting the ICP method, is provided with at least an induction coil and a nozzle, and the nozzle is a ceramic nozzle manufactured by the CVD method.
