Electrical connector

An electrical connector includes an elastomer layer or board and a plurality of fine lead wires embedded in the elastomer layer and extending rectilinearly therein at right angles to both the surfaces of the elastomer layer. Recesses are formed in the elastomer layer around peripheries of openings of through-holes in which the fine lead wires are embedded. The electrical connector further includes two flexible printed circuit boards on both the sides, each including electric contacts to be connected to mating contacts, connection portions each formed with a through-hole passing therethrough, and conductors each electrically connecting the connection portion to the electric contact. When the flexible printed circuit boards and the fine lead wires are electrically connected by vapor reflow soldering, the flexible printed circuit boards and the elastomer layer having the fine lead wires embedded therein are clamped by restraining jigs to prevent from the flexible printed circuit boards from moving away from the elastomer layer. With this arrangement, reliable connection between the fine lead wires and the flexible printed circuit boards can be achieved without need to control the length of the fine lead wires without any risk of the flexible boards being deflected or warped during soldering even if circumferences of portions to be electrically connected are covered by the insulator.
