| 1. A jig for calcining an electronic component, the jig comprising:
a substrate;
a zirconia surface layer of a first material formed at least on a top surface of the substrate;
a metal oxide coated layer of a second material formed at least on a bottom surface of the substrate; and
an intermediate layer formed between the substrate and one of the zirconia surface layer and the metal oxide coated layer,
wherein a thickness ratio of the zirconia surface layer to the metal oxide coated layer is from 3:4 to 20:7, and
wherein a particle size of the metal oxide is from 0.1 to 100 μm.
