Abstract

A method of manufacturing a conductive layer on a support body includes a first process of forming a precursor layer containing at least one of metal particles and metal oxide particles on the support body; a second process of forming a sintering layer by irradiating an electromagnetic wave pulse on the precursor layer; and a third process of compressing the sintering layer. The conductive layer is formed by repeating the first to third processes 'N' times, where 'N' denotes a natural number equal to or greater than 2, on the same location of the support body, and the third process performed in the first to (N−1)th operations includes forming a surface of the sintering layer in an uneven shape.
