Sliding member and method for producing same

A sliding member comprising:

• a soft metal layer formed by stacking a crystal of soft metal, wherein
• a coarse crystal is exposed on a surface of the soft metal layer, and is made of the soft metal,
• the coarse crystal has a particle length of 1.5 μm or more in a plane direction of the surface, and
• a distribution proportion of the coarse crystal is 5 to 50%,
• wherein the distribution proportion is a proportion of a circumscribed rectangle in a unit length of a virtual straight line,
• wherein the circumscribed rectangle is applied to the coarse crystal appearing in a cross section of the soft metal layer,
• the virtual straight line passing through all the circumscribed rectangles in the cross section and parallel to a surface reference line of the soft metal layer is formed,
• an upper side of the circumscribed rectangle is parallel to the surface reference line of the soft metal layer, and
• the surface reference line is an average height of the surface of the soft metal layer appearing in the cross section, and
• wherein a distance from a center of gravity of a circumscribed rectangle of the coarse crystal appearing in a vertical cross section of the surface and having a maximum length in a thickness direction of the soft metal layer to the surface reference line is 25% or less of a thickness of the soft metal layer.
