Patent ID: 7399929

Claim:
A flexible flat cable comprising: multiple conductors arranged to include a signal line and at least one ground line; first and second insular materials sandwiching the multiple conductors from both ends; shield material attached to a side of the first insular material opposite to the multiple conductors, the shield material being conductive via a conductive adhesive agent with the ground line out of the multiple conductors; and a reinforcement board attached to the side of the second insular material opposite the multiple conductors, wherein the multiple conductors, each having a conducting width from about 0.3±0.03mm, arranged in a parallel manner with a pitch of about 0.5±0.05mm, wherein the first insular material is porous polyethylene trephthalate made of, starting from the side affixed to the shield material, a polyethylene trephthalate film, a porous layer having a thickness of about 34 μm, and an insular adhesive layer, and wherein the shield material is made in a laminating manner, starting from the side affixed to the first insular material, of a conductive adhesive layer made of the conductive adhesive agent, a shield layer made of a polymer-based conductive layer less than about 20μm thick that is a prescribed resin formed including air with uniformly dispersed conductive particles, and base film.
