  • Publication number: 20140308460
    Abstract: Provided is a conductive pattern formation method capable of improving conductivity of a conductive pattern. An ink layer 12 is formed by printing a composition (ink) containing metal oxide particles and a reducing agent, and/or metal particles, on a surface of a substrate 10 and the ink layer 12 is heated by photo irradiation or microwave irradiation so that conductivity is expressed on the heated portion and the ink layer 12 is converted into a conductive layer 14. Metal particles and/or metal oxide particles are heated quickly in a short time and air bubbles are generated during photo irradiation or microwave irradiation and voids are generated inside the conductive layer 14, and thus the conductive layer 14 is pressurized by an appropriate pressing machine 16 to crush the voids to improve conductivity of the conductive layer 14 before obtaining a conductive pattern 18.
