It is an object of the present invention to provide a bearing seal not only whose sealing performance is favorable in normal time, but also whose sealing performance can be prevented from being deteriorated when subjected to vibration caused by impact. A bearing seal includes: a ring-shaped outer seal portion 51; a ring-shaped inner seal portion 52 provided inside the outer seal portion 51; a connecting portion 53 for connecting the inner seal portion 52 and the outer seal portion 51; and an inner ring 60 provided at the connecting portion 53. The outer seal portion 51, the inner seal portion 52, and the connecting portion 53 are integrally formed of the same material consisting of an elastic material. The inner seal portion 52 is formed to have rigidity higher than that of the outer seal portion 51, and has a ring-shaped seal surface 52A gradually approaching a ring center axis of the inner seal portion 52 while extending from a ring-shaped base end side connected to the connecting portion 53 toward a distal end side.
