A composition comprises a solvent, and an electroconductive substance and an amphiphilic block copolymers having a polyalkenyl ether repeating-unit structure, or a block copolymer enclosing an electroconductive substance. A black ink composition comprises a fine particulate metal having an average particle diameter of not more than 20 nm, an amphiphilic block copolymer, and a solvent. A method for forming an electroconductive pattern by applying the composition. A method for forming an electroconductive pattern by applying a composition comprises a block copolymer enclosing an electroconductive substance, system to form an electroconductive pattern on the substrate.
