To provide a rolling bearing which can reduce an installation space of an elastic body for imparting a preload, its manufacturing method and a bearing structure.SOLUTION: In a rolling bearing 1 having an inner ring 2, an outer ring 3 and a plurality of rolling bodies 4, the inner ring 2 is a divided bearing ring composed of first and second raceway members 21, 22 which are aligned in an axial direction, and the first raceway member 21 and the second raceway member 22 are connected to each other by a connecting member 6 having a cylindrical main body part 60. In the first raceway member 21, a leaf spring 7 is accommodated in a first recess 210 which is formed at a corner part. The connecting member 6 integrally has a first circular disc part 61 extending in a radial direction from one end part of the main body part 60, and abutting on the leaf spring 7, and a second circular disc part 62 extending in the radial direction from the other end part of the main body part 60, and regulating the relative movement of the main body part 60 in the axial direction with respect to the second raceway member 22.
