To provide a rolling slide member which can be suitably used even in an environment with a low-viscosity lubricant and even under a condition wherein foreign matter is mixed, and to provide a rolling apparatus using the same.
The rolling slide member, having a diamond-like carbon layer with the lubricity on a contact surface with an opposing member, is characterized in that the above diamond-like carbon layer is formed by laminating five layers, in order from the surface side, a carbon layer comprising carbon, a composite carbon layer comprising carbon and one or more elements of tungsten, titanium, molybdenum and silicon, an interlayer comprising one or more elements of tungsten, silicon, titanium and molybdenum, a composite metal layer comprising mainly either tungsten or silicon and chromium, and a metal layer comprising chromium. Consequently, the diamond-like carbon layer hardly delaminate, and thus this member can be suitably used even in an environment with a low-viscosity lubricant and even under a condition wherein foreign matter is mixed.
