The electrical resistivity of a single-crystalline whisker of UPdIn at 4.2 K was measured in magnetic fields up to 35 T applied along the c -axis of the hexagonal structure. The resistivity values become drastically suppressed in magnetic fields where the metamagnetic transitions appear on the magnetization curve. Taking into account these results, Fermi surface nesting due to the noncompensated antiferromagnetic structure with the propagation vector along the c -axis is suggested to be a source of the large values of the electrical resistivity in zero magnetic field.
