A method of forming an electrode pattern includes: forming, on a base material, a seed layer having a pattern corresponding to the electrode pattern; forming an organic material layer on the seed layer; producing an electrode layer transfer sheet by forming an electrode layer on the organic material layer via an electroplating process using the seed layer as a seed; disposing the electrode layer transfer sheet on a substrate on which the electrode pattern is to be formed such that the electrode layer is in contact with the substrate and pressure bonding the electrode layer to the substrate; and in a state in which the electrode layer is pressure bonded to the substrate, removing the base material along with the organic material layer and the seed layer to transfer the electrode layer to the substrate.
