We report the low temperature specific heat of ternary iron-silicide superconductor Lu 2 Fe 3 Si 5 with T c = 6 K down to $T c /20. We find that a normalized specific heat jump at T c , DC/c n T c , is smaller than BCS value of 1.43. We also find that the specific heat divided by temperature C/T sho
