To provide a sensor fixing structure which can be fastened without restrictions of a fixing portion and with which bad influence by resonance can be eliminated.

When measuring vibration generated in a measurement object 10, such as a machine and a vehicle by a sensor 20 equipped with a sensor body 22, such as an acceleration sensor and an oscillation sensor, the sensor 20 is adhered to the measurement object 10 through an intervention member 30 made of high polymer materials having absorption property around the resonance frequency of the sensor 20. Thereby, the sensor can be simply fixed to an optional portion of the measurement object 10 and would be free of the restrictions of the fixing portion. Since vibration of the resonance frequency entering the sensor 20 can be effectively blocked by the intervention member 30, bad influence by resonance can be eliminated, and accurate measurement can be achieved.
