Zusammenfassung:PROBLEM TO BE SOLVED: To provide slurry for a lithium secondary battery positive electrode using water as a dispersion medium and capable of setting a content ratio of a positive electrode active material and a conductive agent in a wider range.SOLUTION: The slurry for lithium secondary battery positive electrode contains: lithium iron phosphate as a positive electrode active material; a conductive agent; a water-soluble polymer as a thickner; a water-dispersing elastomer; a dispersant; and water as a dispersion medium. The slurry contains at least one of salts of phosphorus compounds represented by formulas (1) to (6) as the dispersant.
