<p>This invention provides, using a novel optical firing technique, an electroconductive composition for forming an electroconductive film having good electrical properties, and a circuit board in which a conductor circuit is formed in a highly productive and inexpensive manner from the electroconductive composition. An electroconductive composition that contains electroconductive microparticles in a solvent and that is fired by light irradiation, the electroconductive composition being characterized in containing a photoinitiator or a photoacid generator. According to a preferred embodiment, the electroconductive composition further contains a dispersing agent, and the solvent is an organic solvent, water, or a mixture thereof. A coating obtained by applying and drying the electroconductive composition is irradiated by light using a flash lamp or the like, whereby it is possible to produce a circuit board on which a conductor circuit is formed by firing the electroconductive composition.</p> |
