(57) [Summary] [Problem] To provide lubricating workability comparable to that of a phosphate film treatment even under severe conditions, and to perform a complicated pre-treatment or post-treatment process like a phosphate film treatment To provide an aqueous lubricating composition that does not require an oil. SOLUTION: Water-based lubricity containing a water-soluble or dispersible resin, a metal-containing solid lubricant, and a metal salt of a fatty acid having 20 or more carbon atoms, an ester or a partially saponified ester thereof in water. Composition. A urethane-based resin is preferable as the resin that can be dissolved or dispersed in water, and a solid lubricant containing molybdenum atoms is preferable as the solid lubricant. |
