We have measured the temperature dependences of the magnetic susceptibility in a magnetic field of 1 T and the specific heat in magnetic fields of 0-9 T for Cu_3B_2O_6 single crystals grown by the Floating Zone method. It has been found that a three-dimensional antiferromagnetic order with the spin direction parallel to the bc plane appears at low temperatures below 10 K. The spin entropy is much smaller than the value of the free-spin entropy at temperatures immediately above 10K and recovers to the value of the free-spin entropy at approximately 50 K. Accordingly, we conclude that the two-dimensional magnetic correlation develops with decreasing temperature at low temperatures below 〜50 K, Ieading to the three-dimensional antiferromagnetic phase transition at 10 K.
