Abstract

The present invention provides a transfer substrate for transferring a metal wiring material to a transfer-receiving object, the transfer substrate comprising a substrate, at least one metal wiring material formed on the substrate and an underlying metal film formed between the substrate and the metal wiring material, wherein the metal wiring material is a molded article prepared by sintering, e.g., gold powder having a purity of 99.9% by weight or more and an average particle size of 0.01 μm to 1.0 μm and the underlying metal film is composed of a metal such as gold or an alloy. The transfer substrate is capable of transferring a metal wiring material to the transfer-receiving object even at a temperature for heating the transfer-receiving object of 80 to 300° C.
