Provided are a sliding member and a sliding bearing which can improve the fatigue resistance. A sliding member having a base layer and a coating layer laminated on the base layer, in which the coating layer contains Bi or Sn as a first metal element, a second metal element which is harder than the first metal element and forms an intermetallic compound with the first metal element, C, and unavoidable impurities.

In a deposition method of Ni—P—B system plating film, electroplating is performed in a plating bath containing Ni ions, phosphorous acid ions, alkylamine borane, acetic acid, at least one sort of a primary brightening agent, and a secondary brightening agent including at least one sort of a surface active agent. In the above-mentioned plating bath, concentration of alkylamine borane in said plating bath is 1.37 mmol/L or more, and concentration of acetic acid in said plating bath is 0.70 mol/L or more and less than 2.80 mol/L. Thereby, plating film having high hardness of Hv 700 or more can be deposited with high manufacturing efficiency without baking processing, while reducing occurrence of poor appearance, such as burning and abnormal precipitation, even when current density is increased to 80 A/dm.sup.2 or more to raise deposition rate.
