  We report the pressure effect in Bi2Sr2Ca2Cu3O10+{\delta} (Bi-2223) single
crystal with a small amount of intergrowth of Bi2Sr2CaCu2O8+{\delta} (Bi-2212).
Their superconducting transition temperatures Tcs showed a domelike shape as a
function of pressure, which showed a good agreement with the general relation
between the carrier concentration and Tc. Our experimental results indicate
that high pressure can induce effective carrier doping into the multilayered
high-Tc cuprate superconductor
