The invention relates to a high temperature superconducting tape conductor having a flexible metal substrate that comprises at least one intermediate layer disposed on the flexible metal substrate and comprising terraces on the side opposite the flexible metal substrate, wherein an average width of the terraces is less than 1 [mu]m and an average height of the terraces is greater than 20 nm, and that comprises at least one high temperature superconducting layer disposed on the intermediate layer, which isdisposed on the at least one intermediate layer and comprises a layer thickness of greater than 3 [mu]m. The ampacity of the high temperature superconducting tape conductor relative to the conductor width is greater than 600 A/cm at 77 K.
