The electrical resistivity of the antiferromagnetic dense Kondo compound UCu 5 In has been studied on single-crystalline specimens under hydrostatic pressure up to 2.2GPa. Upon applying pressure, ρ a (T) hardly alters but the other two resistivity components, i.e. ρ b (T) and ρ c (T), show some change in their magnitudes, in both the ordered and paramagnetic regions. The Neel temperature T N =25K is almost independent of pressure, which indicates that the magnetic moments in UCu 5 In are rather well localized.
