PURPOSE:To reduce contact resistance and to improve adhesive strength by arranging a flexible wiring board which has two divided connection terminals on one terminal of a transparent electrode for external connection across an anisotropic conductive adhesive, and making an electric connection by thermocompression bonding. CONSTITUTION:Connection terminals 5 of the flexible wiring board 4 are position- matched on the top surface of the transparent electrode 2 for external connection and then pressed against a heat plate, so that they are joined with the anisotropic conductive adhesive 3 by fusion. In this case, almost all the anisotropic conductive adhesive 3 right under the two divided connection terminals is removed to a part where no pressure is applied, i.e. except to the connection terminals 5 and to a recessed part formed of the two divided connection terminals 5. Consequently, conductive particles of the anisotropic adhesive 3 contact one another closely in the gap among the connection terminals 5 and transparent electrode 2 for external connection to decrease the contact resistance. At the same time, no pressure is applied directly to the anisotropic conductive adhesive 3 right under the recessed part of the connection terminals 5, so there is almost no flow of the adhesive, which is confined to the recessed part, thereby maintaining the adhesive strength by forming a reservoir for the adhesive.
