The present invention provides a method for producing a slurry composition which realizes excellent dispersibility through simple steps and can maintain high dispersibility over a long term. In addition, the present invention provides a slurry composition produced using this method. The present invention provides a method for producing a slurry composition containing an inorganic powder, a polyvinyl acetal resin, and an organic solvent. The method contains the steps of mixing an inorganic powder, a mixed polyvinyl acetal resin (A) and an organic solvent (i) to prepare an inorganic dispersion; mixing a polyvinyl acetal resin (B) and an organic solvent (ii) to prepare a resin solution; and adding the resin solution to the inorganic dispersion.
