Disclosed herein is an aqueous dispersion slurry coating material which has excellent storage stability and which can provide a coating film having excellent surface smoothness. The aqueous dispersion slurry coating material includes: an aqueous medium; and contained therein, resin particles (A) comprising a first resin (a); and resin particles (B) comprising a second resin (b), wherein the value of [volume-average particle diameter DA of resin particles (A)]/[volume-average particle diameter DB of resin particles (B)] is in the range of 0.003 to 0.3. It is preferred that the value of DA is in the range of 0.001 to 3 μm and that the value of DB is in the range of 0.3 to 10 μm. The resin (a) preferably has a Tg of 0 to 100° C., and the resin (b) preferably has a Tg of −50 to 50° C. The aqueous dispersion slurry coating material preferably further includes a surfactant and a curing agent. The resin (a) and the resin (b) are preferably of at least one kind selected from the group consisting of polyurethane resins, epoxy resins, vinyl resins, and polyester resins.
