PROBLEM TO BE SOLVED: To improve the wear resistance while using Bi or Bi alloy in an overlay layer. SOLUTION: An overlay layer 4 is formed on a bearing alloy layer 2 via an intermediate layer 3. The overlay layer 4 is formed of a material containing hard particles of 0.05-25 vol.% in Bi or Bi alloy. The wear resistance of the overlay layer 4 can be improved by containing hard particles while using Bi or Bi alloy.
