Summary:PROBLEM TO BE SOLVED: To provide noble metal paste which can impart coloring or a pattern to the surface of a heat resistant substrate such as a noble metal sintered product, a noble metal matrix, white porcelain and ceramics by being applied and baked thereto, or is used also for the tight adhesion between heat resistant substrates, to provide a method for producing ornaments, and to provide a method for producing a heat resistant product. SOLUTION: The noble metal paste comprises: pure noble metal powder selected from Au, Ag, Pt and Pd or noble metal alloy powder consisting mainly of one or more kinds selected these elements; an organic binder liquid; a lead-free glass frit of ≥0.1%; and bismuth powder of ≥0.1 wt.%, and is used for any one selected from coloring, the impartation of a pattern and tight adhesion by being applied and baked to the surface of a heat resistant substrate.
