Zirconia layered body

A layered body having a structure in which two or more layers containing zirconia containing a stabilizer are layered,

• the layered body comprising at least:
• a first layer containing zirconia having a stabilizer content of higher than or equal to 4 mol %;
• and
• a second layer containing zirconia having a stabilizer content different from that of the zirconia contained in the first layer,
• wherein a difference between the stabilizer content in the first layer and the stabilizer content in the second layer is greater than or equal to 0.5 mol %,
• wherein at least one layer contains one or more elements having a function of coloring zirconia,
• wherein at least a first layer and a second layer contain an element having a function of coloring zirconia and the content or the type of the element having a function of coloring zirconia in the first layer is different from the element having a function of coloring zirconia in the second layer and the layered body is a calcined body.
