PURPOSE:To achieve an analysis on element contained in molten metal in a short time and accurately, simply by immersing a probe into a molten metal. CONSTITUTION:A heat-resistant inflow tube 7 is erected at the tip of probe of a measuring device 1 to form an opening 6 and an void forming member 3 is provided inside. A void 8 is formed along the length of the probe communicating with the inflow tube 7 inside the member 3 and make the inside 3 of the inflow tube 7 and a space in the member 3 void 8 as a whole. A material capable of cooling composing the inside of the member 3 makes up a cooling means 5 to cool the molten metal introduced especially near an electrode 9 while the other electrode 10 located at the position nearer the molten metal to be introduced, namely near the side of the opening 6, and hence there are temperature difference between the two parts. When the apparatus 1 thus obtained is immersed into the molten metal, the molten flows in through the inflow tube 7, the molten metal fills the void 8. Under such a condition, when the apparatus is pulled out of the molten metal, the molten metal is cooled within the void 8 with a temperature difference is given between both the electrodes 9 and 10 so that an electromotive force is generated between the electrodes 9 and 10. The electromitive force is measured to determine contained elements.
