Abstract
A jig for calcining an electronic component including a substrateand a zirconia layercoated on a surface of the substrate characterized in that the zirconia layer including one or more metal oxides forming a liquid phase is calcined for improving peel-off resistance and wear resistance to crystallize the liquid phase after the calcination. In the jig for calcining the electronic component, when the zirconia layer is formed by using an inexpensive method such as an application method, the zirconia layer is not peeled off from the substrate, and grains are not detached.
