Resistivity of a Heusler-type intermetallic paramagnetic compound PrInAg2 is measured precisely down to 50 mK. An empirical equation is well determined as Δρ ∝ + log T between 50 mK and 1 K. The system is expected as an example of the quadrupolar Kondo system, since the Pr3+ (4f2) ion in the material has a non-magnetic doublet ground state Γ3. The results are not consistent with Δρ ∝ ± T1/2 which is expected from the single impurity quadrupolar Kondo model near the ground state.
