To provide a reliable diagnosis technique when diagnosing the state of the lubricant of a rotary machine such as a wind power generator by a state monitor sensor.SOLUTION: The present invention relates to a lubricant diagnosis system including: a lubricant-using apparatus; a lubricant tank for storing a lubricant to be supplied to the lubricant-using apparatus; and a sensor for measuring the characteristics of the lubricant. The system diagnoses the state of the lubricant by using sensor data obtained after a time necessary for air bubbles in the lubricant generated when the apparatus is used to disappear has passed after the lubricant-using apparatus stopped working, the lubricant being generated regularly or irregularly.SELECTED DRAWING: Figure 9 【課題】風力発電機などの回転機械の潤滑油の状態診断を状態監視センサにより行う際に、信頼性が高い診断技術を提供することにある。【解決手段】潤滑油使用機器と、潤滑油使用機器に供給される潤滑油を貯留するための潤滑油タンクと、潤滑油の特性を測定するセンサと、を備える潤滑油の診断システムである。このシステムにおいて、定期的または不定期的に発生する潤滑油使用機器の停止後，機器使用時に発生する潤滑油中の気泡が消滅するのに必要な時間が経過した後に得られるセンサデータを用いて潤滑油の状態診断を行う。【選択図】 図９
