We have investigated current transport properties in two G 1 dBa 2 Cu 3 O 7-δ (GdBCO) coated conductors deposited on different quality of IBAD substrate, i.e., in-plane alignments of the substrate are 1.98° and 2.78°, respectively. From the comparison, J c enhancement has been confirmed in wide temperature and magnetic field region in the sample using highly oriented IBAD substrate, whereas the irreversibility field and shape of pinning force density (F p ) does not change much. Furthermore, higher in-filed J c than that of BaHfO 3 doped GdBCO coated conductor deposited on standard IBAD substrate has also been observed in practical high field region at low temperature. These results indicate that the improvement of in-plane texturing in the substrate is still very effective even in such range of 2 to 3° to improve in-field J c .
