We report detailed study of non-magnetic impurity effects in a two-gap superconductor Lu 2 Fe 3 Si 5 by replacing Lu with Sc. We find that the superconducting transition temperature T c is drastically suppressed by slight substitution of Sc, while lattice constants change linearly with the substitut
