Abstract:
1. A wiring board connection method which connects wiring boards each having a strip-shaped connection terminal for connecting with another substrate, the method comprising: arranging a continuous conductive joint body (i) on adjacent connection terminals of one of the wiring boards, and (ii) in a space between the adjacent connection terminals on the one of the wiring boards; aligning the wiring boards so that the connection terminals face each other with the conductive joint body interposed therebetween; and bonding the connection terminals with each other by heating and then cooling the conductive joint body, wherein: the conductive joint body is a material that generates air bubbles upon being heated; a plurality of the connection terminals are provided in each of the wiring boards; a recessed portion is formed on a surface of at least one of the connection terminals in at least one of the wiring boards, the surface being opposite to the connection terminal of another wiring board; and when the connection terminals are bonded with each other, the conductive joint body is allowed to move so as to gather on the surfaces of the connection terminals where no recessed portions are formed.
