We have investigated the spin state of the one-dimensional edge-sharing chain system Ca2+x Y2-x Cu5 O10 with 0 ≤ x ≤ 1.667 by means of the magnetic susceptibility and specific heat measurements, using the large-size single-crystals. It has been found that the magnetic ground state is an antiferromagnetically ordered state for 0 ≤ x ≤ 1.0, while a spin-gap state seems to be formed for x ≥ 1.5. Accordingly, it appears that the quantum critical point is located between x = 1.0 and 1.5 in Ca2+x Y2-x Cu5 O10.
