PROBLEM TO BE SOLVED: To provide a method for manufacturing a nitride-based ceramic substrate which does not require a thermal treatment step of reducing deformation after a sintering step, can suppress deformation after the sintering step, and can prevent sheet moldings laminated at sintering from being stuck to each other.SOLUTION: A separation layer is formed on one principal surface of a sheet molding so that its area is 95% or less of the area of the principal surface, and the sheet molding is sintered at 1,700-2,000°C in a state where a plurality of sheet moldings are superposed on each other through the separation layer to manufacture a nitride-based ceramic substrate. |
