[Problem] To provide an oil-based solid cosmetic, which has a far superior pore-covering effect than conventional spherical powder, is easily formed into a formulation having an appropriate hardness, does not cause color streaks, and is excellent in terms of usability. [Solution] An oil-based solid cosmetic comprising (a) a solid oil component (a microcrystalline wax, a paraffin wax, etc.) in an amount of 2 to 10% by mass, (b) an organic modified clay mineral in an amount of 2.5 to 8% by mass, (c) a specific polyglycerol-modified silicone (for example, bis-butyldimethicone polyglyceryl-3, etc.) in an amount of 0.3 to 8% by mass, (d) a cationic surfactant in an amount of 0.1 to 2% by mass, and (e) a branched saturated fatty acid having 14 to 24 carbon atoms in an amount of 0.2 to 7% by mass.
