Abstract:
To provide a surface-treated copper foil in which exfoliation of roughened particles in a roughened particle layer arranged on a surface of the copper foil is well suppressed and occurrence of a wrinkle and a stripe when plying-up with an insulation substrate is well suppressed.SOLUTION: A surface-treated copper foil has a copper foil and a roughened processed layer on at least one surface of the copper foil. The roughened processed layer meets one or more selected from the following groups (1) to (6): (1) Roughness Sq ranges from 0.16 μm to 0.30 μm, inclusive; (2) Roughness Ssk ranges from -0.6 to -0.35, inclusive; (3) Roughness Sa ranges from 0.12 μm to 0.23 μm, inclusive; (4) Roughness Sz ranges from 2.20 μm to 3.50 μm, inclusive; (5) Roughness Sku ranges from 3.75 to 4.50, inclusive; and (6) Roughness Spk ranges from 0.13 μm to 0.27 μm, inclusive. The color difference ΔE*ab according to JIS Z8730 of a surface of the roughened processed layer side is smaller than or equal to 65, and the glossiness of the surface of the roughened processed layer side is smaller than or equal to 70%..SELECTED DRAWING: Figure 1
