A material for a positive electrode containing: a positive electrode active material, an inorganic solid electrolyte having conductivity of ions of metals belonging to Group I or II of the periodic table; an auxiliary conductive agent; and a dispersant including a compound having at least one selected from a group of functional groups (I), an electrode sheet for an all-solid state secondary battery and an all-solid state secondary battery for which the material for a positive electrode is used, and methods for manufacturing an electrode sheet for an all-solid state secondary battery and an all-solid state secondary battery. Group of functional groups (I): acidic groups, (meth)acryloyl groups, (meth)acryloyloxy groups, (meth)acrylamide groups, alkoxysilyl groups, epoxy groups, oxetanyl groups, isocyanate groups, cyano groups, and mercapto groups.
