Copper foil provided with carrier, laminate, printed wiring board, and method for fabricating printed wiring board

Provided is a copper foil provided with a carrier which enables, in a laminate produced by laminating a copper foil provided with a carrier on a resin substrate, to peel the ultrathin copper layer from the carrier well. A copper foil provided with a carrier having, in order, a carrier, an intermedia...

description Provided is a copper foil provided with a carrier which enables, in a laminate produced by laminating a copper foil provided with a carrier on a resin substrate, to peel the ultrathin copper layer from the carrier well. A copper foil provided with a carrier having, in order, a carrier, an intermediate layer, and an ultrathin copper layer, wherein, when the surface of the carrier opposite to the ultrathin copper layer is measured using a laser microscope based on JIS B0601-1994, the ten point average roughness Rz of the surface is 6.0 μm or less.
