Claim 10:
11. A method for producing the layered body according to claim 1, comprising:
calcining a green body at 800° C. to 1,200° 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 binder content between the first powder composition layer and the second powder composition layer which exceeds 0.01 wt %.
