Provides insulating films, adhesive films, and flat cables that are excellent in toughness and bonding strength, and can achieve low dielectric rate and low dielectric tangent. In more detail, the insulating film 4 is used for the flat cable 1. This insulating film 4 is made up of polyarylene sulfide resin (A), polyphenylene ether resin (B), and polyarylene sulfide resin (A) and polyphenylene ether resin (B). At least one of the reactive groups of the modified elastomer (C) is formed into a resin composition, wherein the content of the polyarylene sulfide resin (A) in the resin composition is 50 to 93% by mass, The content of the polyphenylene ether resin (B) is 3 to 40% by mass. |
