Zusammenfassung: | Disclosed is a surface treated copper foil, which is capable of favorably reducing the transmission loss even when used in a high frequency circuit substrate, and after laminating with a resin, heating at a predetermined temperature for a predetermined time (at 180? C. for 10 days), the peel strength of the surface treated copper foil and the resin is favorable. Also disclosed is a surface treated copper foil, comprising a copper foil, and a surface treatment layer on one or both sides of the copper foil, wherein the surface treatment layer has a primary particle layer, or has a primary particle layer and s secondary particle layer in this order from the side of the copper foil; the surface treatment layer contains Zn, a deposition amount of Zn in the surface treatment layer is 150 ?g/dm? or more; the surface treatment layer does not contain Ni, or in the case where the surface treatment layer contains Ni, a deposition amount of Ni in the surface treatment layer is 800 ?g/dm? or less; the surface treatment layer does not contain Co, or in the case where the surface treatment layer contains Co, a deposition amount of Co in the surface treatment layer is 3000 ?g/dm? or less; and a ten point average roughness Rz of an outermost surface of the surface treatment layer is 1.5 ?m or less.
