This invention provides a novel cross-linked polyaniline derivative soluble or capable of swelling in general organic solvents, which forms an elastic self-standing film or fibers. The polyaniline derivative substantially comprises a polyaniline having number average molecular weight in a range of from 2,000 to 500,000 represented by the following formula (I) as the main polymer chain, <IMAGE> (I) wherein m and n are 0 or an integer of at least 1, m/(m+n)=0-1, and m+n=10-5,000, and cross-linking units represented by the following formula (II) <IMAGE> (II) wherein X is a direct bond, a substituted or unsubstituted divalent C1-C30 aliphatic hydrocarbon group, a substituted or unsubstituted divalent aromatic hydrocarbon group, a divalent polysiloxane group or a group derived therefrom, or a divalent group derived from a compound having 2 or more repeating structural units, y1 and y2 which may be identical or different denote each a direct bond, <IMAGE> <IMAGE> wherein Z is an oxygen atom or a sulfur atom, Q is an oxygen atom, a sulfur atom or -NH-, R1 is a hydrogen atom, a C1-C4 alkyl group, an alkenyl group, an alkoxyl group, a benzyl group or an aryl group, which may be substituted, and a is 0-2.
