To provide a method for producing fuel improved in ignitability and combustibility by applying a new treatment to carbonized matter, thereby producing fuel utilizable to a pulverized coal combustion furnace, etc.

A fuel producing apparatus 100 includes: a carbonization furnace 110 producing solid carbonized matter C1 by carbonizing biomass B1; a pyrolytic furnace 130 pyrolyzing any one or both (wastes W1) of biomass and wastes to decompose by heating, and producing pyrolytic oil OR; and an impregnation unit 150 impregnating the solid carbonized matter C1 with a first pyrolytic oil OH.
