Zusammenfassung:	PURPOSE:To enable even a small amount of leakage to be detected positively for improving reliability by using a configuration which is in simple structure and achieves an extremely simple maintenance without requiring a dust-proof structure as in the case of use of a microphone. CONSTITUTION:A boiler housing 6 with an airtight wall 1 for retaining an inside of a boiler to be in airtight state is penetrated and a waveguide 7 for taking sound out of it directly is provided. A vibration plate 8 is mounted to an external tip of this waveguide 7, at the same time a vibration sensor 9 is mounted to this vibration plate 8, and detection vibration according to this vibration sensor 9 is recorded in a recorder 12.
