Nuclear spin-lattice relaxation rate T-1(-1) has been measured for the ladder sites of two single crystals Sr14Cu24O41 (Sr14-A,B) by Cu-63 NMR/NQR. The hole localization around 100 K appears as a peak in the T variation of T-1(-1) (NQR). Oil the other hand, it is suppressed in the T-1(_-1)(NMR) data Under the magnetic field H similar to 11 T,and a new peak appears around 20 K. T-1(-1)(NMR) around the peak is more enlarged for Sr14-B than for Sr14-A. Hence, holes on the ladders of Sr14-B tend to be more localized. This is considered to be an origin for the occurence of the magnetic order in Sr14-B Under H similar to 11 T.
