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.

Abstract: A biosignal measurement apparatus that is used by being affixed on a living body is provided with: an affixed part that is a sheet, in which a signal-acquiring section of multiple electrodes and wiring connected to each of the electrodes are formed, and which can be freely expanded, contracted and bent and is adhesive; and a substrate that is connected to the wiring and on which a signal-processing circuit for wirelessly transmitting biosignals obtained through the wiring is mounted. The signal-acquiring section is exposed on the surface of the affixed part and the affixed part and the substrate are stacked so that the back surface of the affixed part faces the substrate.

Abstract: Provided is an electrode sheet allowing easy connection of a wiring that is extended, when required, to a measurement position on a living body. The electrode sheet (main sheet (1), auxiliary sheet (10)) includes a sheet-shaped flexible substrate (2, 11), wirings (3, 12) formed on the flexible substrate (2, 11), electrodes (5, 14) formed on the flexible substrate (2, 11) and electrically connected to the wirings (3, 12), and an insulating layer (4, 13) laid on the flexible substrate (2, 11) in such a manner that the wirings (3, 12) are overlaid with the insulating layer (4, 13) while the electrodes (5, 14) are exposed. The electrodes (5, 14) are formed of a conductive material in which conductive particles are dispersed in a thermoplastic resin.
