Abstract
Provided is a conductive film for antennas, in which a conducting film and a substrate made of a polycarbonate resin material containing a polycarbonate resin are laminated, and the polycarbonate resin contains, as main constituent units, a unit (A) represented by the following formula (1) and/or a unit (B) represented by the following formula (2). The conductive film for antennas has low dielectric characteristics and bendability, can form an antenna with a low transmission loss, and has excellent adhesion to the conducting film. (In the formula (1), Rand Reach independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, and Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom.) (In the formula (2), Rand Reach independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom, Rrepresents a halogen atom, an alkyl group having 1 to 20 carbon atoms, or a cycloalkyl group having 3 to 20 carbon atoms, and n represents an integer of 0 to 10.)
