PROBLEM TO BE SOLVED: To provide a rolling bearing device allowing highly accurate detection of the rotated condition of a rotor. SOLUTION: The rolling bearing device 1 having an outer ring 3 arranged on the side of the outer diameter of an inner ring 2 via a number of rollers 4 comprises a brushless resolver 10 arranged between the inner ring 2 as a rotor and the outer ring 3 as a non-rotor for detecting the rotated condition of the inner ring 2. The brushless resolver 10 outputs a signal having an almost constant amplitude when the inner ring 2 is stopped and outputs a signal having an amplitude changed non-stepwise with the rotated condition thereof when the inner ring 2 is rotated.
