Abstract: [Problem] To provide an electroconductive ink suitable for an inexpensive carbon wiring substrate having a wide strain sensing range, and a carbon wiring substrate in which the electroconductive ink is used.
[Solution] An electroconductive ink characterized by including a carbonaceous electroconductive material (A), a binder resin (B) including a cellulose compound (B1) and a poly N-vinyl compound (B2), and a solvent (C), the electroconductive ink including 0.5-23 parts by mass of the binder resin (B) with respect to 100 parts by mass of the carbonaceous electroconductive material (A), the mass blending ratio of the cellulose compound (B1) and the poly N-vinyl compound (B2) being 80:20 to 40:60, and the solvent (C) including water (C1). A carbon wiring substrate having a wiring pattern formed using the electroconductive ink.

Abstract: Provided are a metal nanowire production method capable of producing long and thin metal nanowires, and metal nanowires produced thereby. A metal nanowire production method comprising, a step for preparing a solution containing a metal salt, a polymer, at least one selected from a group consisting of halides, sulfides, carbonates, and sulfates, and an aliphatic alcohol, and a step for heating and reacting the solution at the temperature of 100° C. to 250° C. for 10 minutes or more while maintaining a practical shear stress applied to the solution at 10 mPa·m or less, wherein, during the heating and reacting step, ultraviolet-visible absorption spectrum change of the solution is measured, and a reaction time is controlled on the basis of the ultraviolet-visible absorption spectrum information.
