Title: Jig for electronic part firing

Abstract: The long-term use of a conventional jig for calcining an electronic component arises a problem such as peel-off of a zirconia surface layer. Even if the performance is not deteriorated in the short-term use, the zirconia surface layer reacts with the electronic component to shorten the life of the jig for calcining the electronic component when the use is prolonged for a longer period of time. A jig for calcining an electronic component is provided which is stable after use of a longer period of time by suitably setting the composition of a zirconia surface layer. For example, in the zirconia surface layer containing zirconia particles and a partially fused-bonding agent, an amount of calcia is made to be 4 to 15% in weight.
