PROBLEM TO BE SOLVED: To provide an electronic parts sintering jig having long-term durability, improved by selecting the kind of metal to be used as a surface layer in order to solve the problem that the conventional jig is short of long-term durability, for example, the surface layer is peeled off from an intermediate layer because the adhesive strength between the surface layer and the intermediate layer is not sufficient. SOLUTION: This jig for sintering electronic parts comprises a base material, the intermediate layer or partially melted intermediate layer which is coated on the surface of the base material and which consists of a metal oxide containing alumina, and the zirconia - calcia - alumina - yttria surface layer or the yttria-stabilized zirconia surface layer formed on the intermediate layer or the partially melted intermediate layer. When the oxide or a composite oxide of metal is used as the surface layer, the adhesive strength between the surface layer and the (partially melted) intermediate layer is enhanced regardless of the kind of metal of the intermediate layer or partially melted intermediate layer so that the jig for sintering electronic parts, which is excellent in long-term durability such as exfoliation resistance, can be obtained. |
