PROBLEM TO BE SOLVED: To provide a conductive pattern material of high conductivity and wide application, a metal particulate pattern material, having a metal particulate absorption region of superior durability, into which metal particulates are dispersed in high concentration, and to provide a pattern formation method by which they are manufactured in a simple process of high productivity. SOLUTION: After a pattern comprising hydrophilic/hydrophobic regions is formed on a surface of a substrate, metal ions or metal salt is added to the hydrophilic region. Then the metal ion or that in the metal salt is reduced to form a metal thin film or the metal particulate absorption region, thereby the conductive pattern material or the metal particulate pattern material is constituted. The pattern formation method comprises a step for forming the pattern comprising the hydrophilic/hydrophobic regions on the surface of the substrate; a step for adding the metal ion or the metal salt to the formed hydrophilic region; and a step for reducing the metal ion or that in the metal salt and then depositing a metal to form a metal (particulate) film pattern.
