Abstract

The present invention provides a method for producing a slurry composition which realizes excellent dispersibility through simple steps. 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 inorganic powder, a polyvinyl acetal resin, and an organic solvent, the method comprising the steps of: mixing inorganic powder, a polyvinyl acetal resin (A) and an organic solvent for inorganic dispersion to prepare an inorganic dispersion; mixing a polyvinyl acetal resin (B) and an organic solvent for resin solution to prepare a resin solution; and adding the resin solution to the inorganic dispersion, the polyvinyl acetal resin (A) having a polymerization degree of 200 to 600, the polyvinyl acetal resin (B) having a polymerization degree of 800 to 4000, and an amount of the polyvinyl acetal resin (A) used in preparation of the inorganic dispersion being 0.1 to 20 parts by weight relative to 100 parts by weight of the inorganic powder.
