To provide a holder for rolling bearing which can extend its lubricating life even though it is a small size rolling bearing used under a high speed and a high temperature condition.

In a resin holder 4 used in a rolling bearing, and holding a rolling body 34 rotatable in a holding part 7, the inner surface of the holding part 7 is made in a coarse surface to form an uneven surface, and the surface area of the inner surface 7a is increased to enhance the holding force of a base oil. As a result, even though the bearing is used in a high speed rotation, the base oil can be maintained in the holding part 7 to hold the rolling body 3, an oil film can be formed to a track surface and to the rolling body 3, by the holded based oil, and the service life of the bearing can be extended.
