Abstract: Cu-sheathed SmFeAsO<sub>1-x</sub>F<sub>x</sub> tapes were fabricated by the ex situ powder-in-tube method. A series of low-temperature (400 &#x00B0;C) hot-pressing process and ordinary sintering process was applied on the tapes, respectively. A transport critical current density (J<sub>c</sub>) value of 2.37 &#x00D7; 104 A cm-2 (at 4.2 K and self-field) was achieved in the Cu-sheathed SmFeAsO<sub>1-x</sub>F<sub>x</sub> hot-pressed tapes. This is the first time that a large transport J<sub>c</sub> is obtained in Cu-sheathed 1111-type wires. The scanning electron microscopy also revealed that the low-temperature hot-pressing technique is effective in preventing the reaction layer between Cu-sheath and superconducting core.
