PROBLEM TO BE SOLVED: To improve connection reliability increasing the number of processes at the time of connecting fellow connection terminals of a minute pitch by using an anisotropic conductive material. SOLUTION: At the time of connecting fellow connection terminals 3, 4 of a minute pitch by using an anisotropic conductive material, an uneven part 6 having a smaller difference in interval and height than a diameter of a conductive particle 1 is formed on the top of a projection 2 for connection so as to check a leak of conductive particles 1 by this uneven part 6 and a surplus of resin and air bubbles generating during heating leak outside of a connection terminal. Thereby, conductive particles 1 and only resin of the anisotropic conductive material remain in the connection part so as to improve connection reliability. The uneven part 6 can be easily formed by formation of a specific pattern 5a and applying electrolytic soldering. |
