Claim:
1. A conductive-layer-integrated flexible printed circuit board, comprising: (A) an electromagnetic-shielding conductive layer; (B) an insulator film; and (C) a wiring-pattern-equipped film, (A) the electromagnetic-shielding conductive layer, (B) the insulator film, and (C) the wiring-pattern-equipped film being laminated in this order, (B) the insulator film having a thickness of from 5 μm to 100 μm containing at least (a) a binder polymer and (b) a black coloring agent containing a perylene compound and having a reflectance of 5% or higher in a reflective range within an infrared range, wherein (B) the insulator film contains (c) a flame retarder that is substantially undissolvable in an organic solvent, the flame retarder being selected from at least one member of the group consisting of a phosphinate, a melamine cyanurate, and a boehmite aluminum hydroxide, and wherein (A) the electromagnetic-shielding conductive layer comprises a paste comprising a resin and silver or nickel particles dispersed therein.
