[PROBLEMS] To provide a solid lubricant that retains lubricating oil, which has excellent lubrication performance, can be operated even at high speed rotation with a long life, and can be relatively simplified in production process, and can be foamed to meet the demand for cost reduction. A solid lubricant sealed bearing is provided. A foamed solid lubricant-enclosed bearing in which a foamed solid lubricant 37 is encapsulated in a bearing 31, wherein the foamed solid lubricant 37 includes a lubricating component and a resin component as essential components, and the resin component It is a solid that has been made porous by curing and foaming, and the foamed solid lubricant has a resin component made of a resin having rubber-like elasticity or rubber, and has a leaching property of a lubricating component by deformation due to external force, The resin component is a polyurethane resin.
