The electronic structures of Sr{sub 14{minus}x}Ca{sub x}Cu{sub 24}O{sub 41} are calculated within the local-density approximation. Around the Fermi energy there exist quasi-one-dimensional bands originated from the ladder and chain layers. The nearest-neighbor interladder hoppings are estimated to be 5{endash}20{percent} of the intraladder ones. Possible effects of Ca substitution on electronic structures and charge distribution are also discussed. {copyright} {ital 1997} {ital The American Physical Society}
