To provide a bearing assembly having an electric power generating capability, that can be assembled compact in size and easily incorporated in a drive transmission system of an internal combustion engine, the bearing assembly having an electric power generating capability includes a rolling bearing 1 including an outer race 7 and an inner race 6 rotatable relative to the outer race 7, and an electric power generator 2 interposed between the inner and outer races 6 and 7 for generating an electric power by a rotation of the inner race 6 relative to the outer race 7. This bearing assembly may be used as a bearing in the drive transmission system of the internal combustion engine for rotatably supporting, for example, a crankshaft 4.
