Sliding member

A sliding member comprising:

• a resin overlay layer on a sliding-surface side of a bearing alloy layer,
• wherein the resin overlay layer includes
• a resin binder, and
• 20% by volume or more of solid lubricant particles with an anisotropic shape dispersed in the resin binder,
• when a virtual straight line that is parallel to the sliding surface is defined as being located at 0°, a virtual axis that is perpendicular to the sliding surface is defined as being located at 90°, an angle formed by the straight line and the major axis of the particles is defined as θ, and the total number of the particles included in a given observation region of the resin binder is defined as N,
• a rate R1=N1/N of the number N1 of first particles with the angle θ being 70°≤θ≤90° from among the particles is 3%≤R1≤20%, and
• a rate R2=N2/N of the number N2 of second particles with the angle θ being θ≤20° from among the particles is 35%≤R2≤65%.
