To provide a method for producing ceramic sheets capable of further improving productivity while suppressing unevenness of quality between ceramic sheets obtainable.

The method for producing ceramic sheets includes a step (I) of making a laminated body by overlapping green sheets for ceramic sheets through ceramic porous spacers with each other, and arranging a sheet surface of the green sheets in a direction along the vertical direction; and a step (II) of firing the green sheets contained in the laminated body in the step (I).
