Abstract: The present invention provides a nickel nanowires-containing paste having an adequately high thermal curing rate even under comparatively low temperature, which is excellent in functional properties such as an electrical conductivity, strength properties (in particular, a bending property), a water-resisting property, a salt water-resisting property and electromagnetic-wave shielding properties, from which a cured structure excellent in an electrical conductivity can be obtained even if it is stored for a long time. The present invention relates to a paste comprising nickel nanowires, an alkoxy-alkylated polyamide and a glycol.
