Claim 11:
12. A method for producing the layered body according to claim 1 comprising:
calcining a green body at a temperature of higher than or equal to 900° C. and lower than 1,150° C.,
wherein the green body has a structure, in which two or more powder composition layers consisting of a powder composition containing stabilizer-containing zirconia and a binding agent are layered, includes at least
a first powder composition layer containing a binding agent and zirconia which has a stabilizer content of higher than or equal to 4 mol % and
a second powder composition layer containing a binding agent and zirconia which has a stabilizer content different from that of the zirconia contained in the first powder composition layer, and contains one or more elements having a function of coloring zirconia, and

has a difference in a binding agent content between the first powder composition layer and the second powder composition layer which exceeds 0.01 wt %.
