(57) [Problem] To provide a phosphorus-based lubricant which hardly corrodes metals and has excellent extreme pressure properties. SOLUTION: The present invention provides a lubricating base material comprising an organic molybdenum compound as a component (A) and a component (B). The following general formula (B): (Wherein, R a , R b and R c represent a hydrocarbon group, m is 0 or a number of 1 or more, k is a number of 1 or more, n is a number of 1 to 2, p is 0 or 1 represents a lubricating composition. The organic molybdenum compound is preferably a sulfurized oxymolybdenum thiocarbamate, a sulfurized oxymolybdenum thiophosphate, or a reaction product of an amine and a molybdenum compound. |
