A copper-clad laminate is composed of a copper foil and an aromatic polyimide film placed thereon, in which the copper foil is bonded to the polyimide film at a bonding strength of >=500 N/m and the polyimide film shows a light transmittance of >=40% for a light of wavelength of 600 nm and a haze of >=30% [the light transmittance and haze are values measured after the copper foil is removed by etching].
