We measured the complex conductivity at the frequencies from 0.2 THz to 1.0 THz in the under-doped Pb 1 − y Sr2Y 1 − x CaxCu 2 + y O 7 + δ (Pb1212) epitaxial film with terahertz time-domain specteroscopy. By analyzing temperature and frequency dependence of the complex conductivity, we found that the superconducting fluctuation persists up to 12 K above Tc, onset. Compared with previous reports, the superconducting fluctuation in Pb1212 is observed shorter temperature range than Bi2Sr2CaCu2O 8 + δ and La 2 − x SrxCuO4. This is ascribed to the lower anisotropy of Pb1212.
