PROBLEM TO BE SOLVED: To provide a lubricant coating measurement device for measuring coating status of lubricant with high accuracy and reliability. SOLUTION: This lubricant coating measurement device includes a light source 40 which irradiates contact portion on a pair of objects with light to generate interference fringe, a spectroscope 36 for generating spectral image of the interference fringe, a microscope 38 for magnifying the spectral image generated by this spectroscope, a high-speed camera 34 for making fast photography of the spectral image magnified by the microscope, a high-speed camera transfer means 46 for moving the high-speed camera along the contact portion, and a computing means 50 for measuring status of oil film from the fast photography data obtained from the high-speed camera.
