NOVELTY - Electroconductive patterned material is manufactured by forming photoresist layer (a) consisting of photosensitive resin composition on electroconductive layer (20) of electroconductive material (1) which contains silver nanowire, and 3D crosslinked structure provided on a surface of base material (10), exposing pattern (b), developing the pattern exposure region and removing photoresist layer of light-exposure region or non-light-exposure region (c), dissolving and removing silver nanowire in the region which is not coated with the resist layer (d), and removing the resist layer.    USE - Manufacturing method of electroconductive patterned material for touch panel, solar cell (claimed), display electrode, electromagnetic wave shield, organic electroluminescent (EL) display electrode, inorganic EL display electrode, electronic paper, flexible display electrode, integrated solar cell, LCD device, and display apparatus with touch panel function.    ADVANTAGE - The matrix has high electroconductivity and film strength.    DETAILED DESCRIPTION - Electroconductive patterned material is manufactured by forming photoresist layer (a) consisting of photosensitive resin composition on electroconductive layer (20) of electroconductive material (1) which contains silver nanowire with average short axis diameter of less than or equal to 150 nm, and 3D crosslinked structure of formula -M1-O-M1- (1) provided on a surface of base material (10), exposing pattern of photoresist layer (b), developing the pattern exposure region of photoresist layer and removing photoresist layer of light-exposure region or non-light-exposure region to form pattern on the surface of electroconductive layer (c), dissolving and removing silver nanowire in the region which is not coated with the resist layer to form non-conductive region (d), and removing the resist layer in an aqueous solution which contains organic alkali or alkali metal carbonate (e).    M1=Si, Ti, Zr, or Al.    An INDEPENDENT CLAIM is included for electroconductive pattern material.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the electroconductive material.
