The effect of Cd substitution for Ca in Bi2Sr2Ca2Cu3Oy has been studied using the rapid-quenching-after-rapid-melting technique. The zero resistivity temperature Tc(endpoint) increased and tailing of transition vanished with increased doping of Cd. The film with the composition Bi2Sr2Ca1.6Cd0.4Cu3Oy exhibited a Tc(endpoint) value of 87 K without tail. Further substitution of Cd for Ca brought about lowering in the Tc until finally no superconductivity transition was shown above 20 K, because a semiconducting phase with c0=2.5 nm formed instead of a c0=3.0 nm phase.
