La_<1.8>Sr_<0.2>CuO_4 (LSC) superconducting polycrystalline films with onset T_c of 32 K are fabricated using the sputtering method. By observing current voltage curves, the (100)-plane films are found to contain weak-link type Josephson-junctions in the film. The electrical resistivity and the maximum DC Josephson current in the films are also measured. Origins of the observed Josephson-junctions are discussed and compared with that of BaPb_<(1-x)>Bi_<(x)>O_3. The LSC polycrystalline films are expected to be more useful than BPB films because of their higher T_c.
