PROBLEM TO BE SOLVED: To sufficiently lower a Q-value and impress large electric power by arranging a hollow tube in the vicinity of a resonator loop conductor, and introducing water or electrolytic solution therein. SOLUTION: For the member of a tube 3 arranged in the vicinity of a loop conductor 1, for example, polyethylene not disturbing resonance mode is mentioned, The tube 3 is formed into a coil so as to be able to circulate solution in the interior, and the tube is filled with water, hydrochloric acid or sodium hydroxide water solution, or the like. The arranged position of the tube 3 can be wherever the inner face, the outerface, the side of the loop conductor. By regulating the total capacity of water or electrolytic solution existing in the vicinity of the loop conductor 1, an optional Q-value can be set. Further, the liquid in the tube is not necessary to flow at measurement, but measurement while flowing is favorable, because heat is radiated and large electric power can be impressed to irradiate strong electromagnetic wave to a sample.
