Abstract: Provided are: a solid lubricant having a low friction coefficient and excellent abrasion resistance; and a sliding member having this solid lubricant embedded therein. The solid lubricant (4) has a sea-island structure, comprising: a sea phase as a continuous phase, containing a hydrocarbon-based wax and a polyethylene resin; and an island phase as a dispersion phase, containing a low-molecular weight tetrafluoroethylene resin, a higher fatty acid salt, a phosphate of basic nitrogen-containing compound, and zinc stannate. A high-molecular weight tetrafluoroethylene resin is contained in this continuous-phase sea phase in a fibrous and mesh state. The hydrocarbon-based wax content is 30-60 vol %, the polyethylene resin content is 3-10 vol %, the low-molecular weight tetrafluoroethylene resin content is 10-30% vol %, the higher fatty acid salt content is 20-40% vol %, the basic nitrogen-containing compound phosphate content is 0.5-5 vol %, the zinc stannate content is 0.5-5 vol %, and the high-molecular weight tetrafluoroethylene resin content is 1-10 vol %.
