NOVELTY - Patterned electroconductive material is manufactured by electroconductive layer forming process (a) performed by providing electroconductive layer (16) which contains metal nanowire with average short axis length of less than or equal to 150 nm, and binder which contains 3D crosslinked structure, on a surface of base material (12), solution provision process (b) performed by reacting electroconductive layer with a solution which dissolves the electroconductive layer in a pattern, and electroconductive layer removal process (c) performed by removing electroconductive layer.    USE - Manufacturing method of patterned electroconductive material for touch panel, solar cell (all claimed), electrode for display, electromagnetic wave shield, electrode for organic electroluminescent (EL) displays, electrode for inorganic EL displays, electronic paper, electrode for flexible displays, integrated solar cell, LCD device, and display apparatus with touch-panel function.    ADVANTAGE - The material has excellent durability, insulation between wiring is favorable, and time-dependent decline in insulation property is suppressed.    DETAILED DESCRIPTION - Patterned electroconductive material is manufactured by electroconductive layer forming process (a) performed by providing electroconductive layer which contains metal nanowire with average short axis length of less than or equal to 150 nm, and binder which contains 3D crosslinked structure of formula -M1-O-M1- (I), on a surface of base material, solution provision process (b) performed by reacting electroconductive layer with a solution which dissolves the electroconductive layer in a pattern, and electroconductive layer removal process (c) performed by removing electroconductive layer on the area where the solution is applied. The patterned electroconductive material has conductive region consisting of patterned electroconductive layer on a base material, and non-conductive region where electroconductive layer is not provided.    M1=Si, Ti, Zr, or Al.    An INDEPENDENT CLAIM is included for patterned electroconductive material comprising base material, patterned conductive region consisting of binder and electroconductive layer, and non-conductive region.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional illustration of the manufacturing process of electroconductive pattern material.    Base material (12)    Middle layer (14)    Electroconductive layer (16)    Photosensitive resist layer (18)
