Abstract	Possibility of boron substitution for Bi and the substitution effect on superconductivity is investigated for the Bi-2212 phase of Bi-Sr-Ca-Cu-O. From X-ray diffraction study, it is found that samples in the (Bi$_{2−x }$B$_{x}$)Sr$_{2}$CaCu$_{2}$O$_{z}$ system are mainly of the single 2212 phase in a composition range of 0.0≤x≤0.6, and both of the lattice parameters a and c change with increasing x up to 0.6. From measurements of the magnetic susceptibility and the electrical resistivity, the superconducting transition temperature is found to increase up to 0.6 with increasing x. These results are considered to show that boron is substitutable for Bi up to x=0.6 in the (Bi$_{2−x }$B$_{x}$)Sr$_{2}$CaCu$_{2}$O$_{z}$ system and that the boron substitution causes the number of hole-carriers to decrease in this system.
