A bearing seal that has excellent sealing ability in normal use and in which the sealing ability is prevented from worsening even if vibration caused by an impact is applied to the seal. The bearing seal has a ring-like outer seal section (51), a ring-like inner seal section (52) provided inside the outer seal section (51), a connection section (53) for connecting the inner seal section (52) and the outer seal section (51), and an inner ring (60) provided at the connection section (53). The outer seal section (51), the inner seal section (52), and the connection section (53) are integrally formed from the same material of an elastic body. The inner seal section (52) has higher rigidity than the outer seal section (51) and has a ring-like seal surface (52A) that gradually approaches the ring center axis of the inner seal section (52) from the ring-like base end side, connected to the connection section (53), toward the fore-end side.
