Abstract
(EN) [Problem] To provide: a copper-clad layered body which, when applied to a flexible circuit board, is capable of suppressing transmission loss and achieving good volume resistivity and high adhesion between a low-dielectric resin film and a copper plate layer; and a method for producing the same. [Solution] This copper-clad layered body is characterized by: comprising a low-dielectric resin film having a relative permittivity of 3.5 or less and a dielectric loss tangent of 0.008 or less at a frequency of 10 GHz, and an electroless copper plating layer laminated on at least one surface of the low-dielectric resin film; the weighted average size of crystallites in the electroless copper plating layer being 25 to 300 nm; and the adhesion strength between the resin film and the electroless copper plating layer being 4.2 N/cm or more.
