Provided are an inorganic substance powder-filled resin composition having uniform dispersibility of inorganic substance powder and providing stable mechanical properties after forming even when the inorganic substance powder is highly filled and a formed article using the inorganic substance powder-filled resin composition. Provided is an inorganic substance powder-filled resin composition including a thermoplastic resin and inorganic substance powder in a mass ratio of 50:50 to 10:90, in which a neutralized product of a polymer made of 50% by mole to 100% by mole of an α,β-unsaturated carboxylic acid and 0% by mole to 50% by mole of another monomer as constitutional units is added. A formed body is prepared using this inorganic substance powder-filled resin composition.
