Manufacturing method of conductive layer

Abstract

An object of the present invention is to provide a manufacturing method of a conductive layer, in which storage stability and jetting stability of an ink are excellent and a conductive layer having excellent conductivity can be formed. The manufacturing method of a conductive layer of the present invention includes a deaeration step of deaerating a conductive ink accommodated in an ink container and a conductive layer forming step of, with an ink jet recording method, applying the deaerated conductive ink onto a substrate by jetting the deaerated conductive ink from a nozzle to form a conductive layer, in which the conductive ink contains at least one material selected from the group consisting of a metal salt, a metal complex, and metal particles, and in a case where a dissolved oxygen amount in the conductive ink before the deaeration step is denoted as a dissolved oxygen amount A and a dissolved oxygen amount in the deaerated conductive ink after the deaeration step is denoted as a dissolved oxygen amount B, a value obtained by subtracting the dissolved oxygen amount B from the dissolved oxygen amount A is larger than 15 mg/L.
