PROBLEM TO BE SOLVED: To obtain a monodispersion organic electroconductive fine particles having uniform shapes and a narrow particle diameter distribution, and further to provide an electroconductive joint structure by using the electroconductive fine particles. SOLUTION: This electroconductive fine particles are obtained by using polymer articles having 0.1-10μm particle diameters as seed particles, allowing the seed particles to absorb a monomer in an amount of 10-500 times as much as that of the seed particles expressed in terms of weight, polymerizing the monomer to provide monodispersion fine particles, and subjecting the resultant monodispersion fine particles to a treatment for making the particles electroconductive. The electroconductive joint structure is obtained by using the electroconductive fine particles.
