To provide a bearing capable of suppressing a degradation in conductive characteristics of a brush while forming an electrical path between an inner ring and an outer ring.
A first member 11 has a ring shape centering around an axis P. A second member 12 has a ring shape centering around the axis P, and faces the first member 11 in a radial direction centering on the axis P. Rolling elements 13 are placed between the first and second members 11, 12 in a radial direction. A conductive member 14 fixed to either one of the first and second members 11, 12, extends from the one toward the other one, and faces the other one in an axial direction along the axis P. A conductive brush 15 intervenes between the conductive member 14 and the other one in an axial direction, and contacts these members. On a surface of the other one facing the one, a groove 1221 open on the side of the conductive brush 15 is formed, and the other one contacts the conductive brush 15 in the groove.
