<p>Disclosed are copper foil with excellent bending ability when used in a copper-clad laminate plate, and a copper-clad laminate using said copper foil. The copper foil is 5-30µm thick, has surface roughness of Ra?0.1µm in the direction parallel to the direction of rolling, and at 350°C has a work hardening exponent of 0.3 or greater and 0.45 or less 0.5 hours after annealing.</p> |
