PROBLEM TO BE SOLVED: To provide a sintered metal bearing capable of restraining generation of an abnormal sound such as a squeal sound, while exhibiting a high sliding characteristic. SOLUTION: The sintered metal bearing has a sliding surface 3 with a shaft 2. The sintered metal bearing is provided with: a sintered metal bearing body 5 that is formed from a different metal structure than the shaft 2 and has many internal air holes 4; and a resin film 6 that is formed on a prescribed surface of the bearing body 5 and constitutes the sliding surface 3. Hereat, the resin film 6 is formed so as to leave surface openings 7 that connect with the internal air holes 4, and upon relative sliding against the shaft 2, a part 10 of the film detaches from the bearing body 5 and adheres to the surface of the shaft 2.
