PROBLEM TO BE SOLVED: To provide an oil state control device that appropriately performs reduction (regeneration) of an antioxidant when controlling a state of antioxidant-containing oil.SOLUTION: An oil state control device for controlling a state of oil which contains an antioxidant and is used as lubricant or hydraulic oil, comprises a content measurement part for measuring a content of an antioxidant in oil, and a reduction part for reducing oxide in the antioxidant. The reduction part includes a hydrogen supply part for supplying hydrogen to oil. The hydrogen supply part controls a hydrogen supply amount to oil on the basis of a measurement result of the content of the antioxidant measured by the content measurement part. Therefore, the oil state control device can appropriately supply hydrogen to be used to regenerate (reduce) oxide in the antioxidant, and appropriately reduce (regenerate) the oxide in the antioxidant when controlling a state of antioxidant-containing oil.SELECTED DRAWING: Figure 1 【課題】酸化防止剤を含有する油の状態を制御するにあたり、酸化防止剤の還元（再生）を適切に行う油状態制御装置を提供する。【解決手段】酸化防止剤を含有する油であって潤滑油または油圧油として用いられる油の状態を制御する油状態制御装置は、油における酸化防止剤の含有率を測定する含有率測定部と、酸化防止剤の酸化物を還元する還元部と、を備える。還元部は、油に対して水素を供給する水素供給部を備える。水素供給部は、含有率測定部による酸化防止剤の含有率の測定結果に基づいて、油に対する水素供給量を制御する。よって、この油状態制御装置によれば、酸化防止剤の酸化物の再生（還元）に用いる水素を適切に供給することが可能となり、酸化防止剤を含有する油の状態を制御するにあたり、酸化防止剤の酸化物の還元（再生）を適切に行うことができる。【選択図】 図１
