Superconductivity has been observed in a spin-ladder compound Ca_{13. 6}Sr_{0. 4}Cu₂₄O_41+δ having Cu₂O₃ ladder-layer. Electrical resistivity measurements show T_c appears at 7 K at 1. 5 GPa and disappears above 6 GPa after having maximum T_c of 12 K at 3 GPa. The bulk superconductivity was confirmed by AC susceptibility measurements. The electrical resistivity measurements for single crystals are also performed. The anisotropy of the electrical resistivity between a-axis and c-axis are reduced under pressure.
