<p>An electronic component burning jig comprising a base (11) and a zirconia layer (12) with which the surface of the base is characterized in that the zirconia layer containing one or more metal oxides forming a liquid phase is fired and the liquid phase (15) is crystallized after the firing to improve the separation resistance and wear resistance. Even when the zirconia layer is formed by a low-cost method such as coating, the zirconia layer is not separated from the base and no particle comes off the zirconia layer.</p>
