PROBLEM TO BE SOLVED: To reduce cost and enhance a magnetic shielding effect by reducing the number of components of members constituting a magnetic circuit for magnetic shielding in a bearing provided with a rotary sensor. SOLUTION: An outer ring member and a magnetic bypass member to be force-fitted into its internal circumferential face are constituted of an annular-portion bypass member 13 consisting of a single component formed integrally by combining mutually. In that bypass portion 15, a V-shaped bent part 20 is formed in the direction of separating from a magnetometric sensor 24, and a path for leakage flux is kept away from the magnetometric sensor 24.
