CONDUCTIVE WIRING MATERIAL, MANUFACTURING METHOD OF WIRING SUBSTRATE AND WIRING SUBSTRATE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a conductive wiring material, a manufacturing method of a wiring substrate and a wiring substrate thereof. SOLUTION: The manufacturing method of the wiring substrate includes a step of printing a wiring material including a plurality of first metal nano particles and second metal nano particles of particle sizes smaller than those of a plurality of the first metal nano particles and can fill spaces of the first metal nano particles with the molten second metal nano particles by low temperature-sintering on a base film, and a step of sintering at a low temperature the base film on which the wiring material is printed, and the second metal nano particles are molten by the low temperature-sintering and the spacing of the first metal nano particles are filled therewith.
