There is provided an electron conductive and corrosion-resistant material 3 containing titanium (Ti), boron (B) and nitrogen (N) in an atomic ratio satisfying 0.05≦[Ti]≦0.40, 0.20≦[B]≦0.40, and 0.35≦[N]≦0.55 (provided that [Ti]+[B]+[N]=1). Further, there is provided a method of manufacturing an electron conductive and corrosion-resistant material 3, wherein boron nitride powder adheres to the surface of a substrate 2 of which at least the surface is made of titanium or a titanium alloy, and is then heated. Furthermore, there is provided a method of manufacturing an electron conductive and corrosion-resistant material 3, wherein the surface of a substrate 2 of which at least the surface is made of titanium or a titanium alloy is borided and then heated. In addition, there is provided a method of manufacturing an electron conductive and corrosion-resistant material 3, wherein a TiB2 layer formed of TiB2 particles is formed by spraying TiB2 powder onto a metal substrate 2 and then nitriding the TiB2 layer.
