Abstract(in English) We have prepared planar-type grain boundary junctions using Ba_ 1-x>K_xBiO_3(BKBO) thin films deposited on SrTiO_3(STO) bicrystal substrates by the RF magnetron sputering method,and investigated their properties.The current-voltage characteristics of the junctions were those of superconductor-insulatorsuperconductor (SIS) junctions and both the Josephson current and the energy gap were observed clearly.The critical current density of the junction was 550A, cm^2 at 4.2K and the I_cR_n product was 2.2mV.A magnetic field applied perpendicular to the substrate modulated the critical current,which gave a clear Fraunhofer pattern.
