PURPOSE: A Mo-based mixture and a surface treated steel sheet using the same of which anti-blackening properties and electric conductivity are excellent are provided to obtain excellent anti-blackening properties and electric conductivity even after treating the steel sheet. CONSTITUTION: A Mo-based mixture comprises 1-10 wt% of a molybdenum compound, 1-10 wt% of polyethylene glycol, 1-10 wt% of a boron compound, and the rest of water. The mixture forms a blackening property improved film. The molybdenum compound is selected from a group composed of ammonium molybdate, phosphorus sodium molybdate, and sodium molybdate. The boron compound is selected from a group composed of a boric acid, sodium borate, a boron oxide, and an organic boron compound.
