PURPOSE:To facilitate the connection of fine-pitch terminals by a method wherein a region, positioned facing LSI element lead terminals on a film base, is constituted of two portions, one provided with through-holes and the other not. CONSTITUTION:Through-holes 3 provided in a film base 1 are positioned facing lead terminals groups 7-1 with gasp between the terminals relatively wide as shown in the left-side portion of the figure. No through-holes or slits are provided in the other portion facing a lead terminals group 7-2 with gaps between the terminals very fine. It is so designed that, when the film base 1 is cut along lines 4, the terminals belonging to the lead terminals groups 7-1 may protrude from an edge of the film base 1 while those belong to the lead terminal groups 7-2 remain contained within the film base 1. |
