Zusammenfassung:	PROBLEM TO BE SOLVED: To make improvable the measuring accuracy and measuring sensitivity by forming at least a part of a resonator housing out of a material having a small thermal expansion coefficient. SOLUTION: An inside space 7 of a hollow cylindrical body 6 of a resonator housing 4 is arranged symmetrically to a cigarette continuous body 1, and a cover 8 is fastened to the hollow cylindrical body 6 with a screw. The hollow cylindrical body 6 and the cover 8 are formed of a material having a small thermal expansion coefficient, for example, an alloy of about 64% of iron and about 36% of nickel. A temperature of the resonator housing 4 is detected by a temperature detector 9, and a heating transistor 11 is controlled to control the temperature constant. Thus, a geometrical shape of the resonator housing 4 becomes constant, and excellent constancy is obtained as a measuring result. The formation of a corrosive material is reliably checked by evaporating a thin gold layer 12 in an inside space 7 to check a harmful skin effect.
