The invention is to provide a positive electrode material for sodium batteries, which has high operating potential and enable charging and discharging at high potential, and a method for producing thereof. Disclosed is a positive electrode material for sodium batteries, comprising positive electrode active material particles represented by the following general formula (1), and an electroconductive carbonaceous material that coats at least part of the surface of the positive electrode active material particles: General Formula (1): Na x M y (AO 4 ) z (P 2 O 7 ) w wherein M is at least one selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn; A is at least one selected from the group consisting of Al, Si, P, S, Ti, V and W; x is a value that satisfies 4‰¥x‰¥2; y is a value that satisfies 4‰¥y‰¥1; z is a value that satisfies 4‰¥z‰¥0; w is a value that satisfies 1‰¥w‰¥0; and at least one of z and w is 1 or more. |
