The present invention relates to a metal wiring, to be formed on a flexible substrate, including a sintered body of silver particles. The sintered body constituting the metal wiring has a volume resistivity of 20 μΩ.Math.cm or less, hardness of 0.38 GPa or less, and a Young's modulus of 7.0 GPa or less. A conductive sheet provided with the metal wiring can be produced by applying/calcinating, on a substrate, a metal paste containing, as a solid content, silver particles having prescribed particle size and particle size distribution, and further containing, as a conditioner, an ethyl cellulose having a number average molecular weight of 10,000 or more and 90,000 or less. The metal wiring of the present invention is excellent in bending resistance with change in electrical characteristics suppressed even through repetitive bending deformation.
