We report the first dHvA study in plutonium compound PuIn$$_3$$ with the cubic AuCu$$_3$$ type structure, which can be regarded as a reference compound of PuCoGa$$_5$$. The result of the angular dependence of the dHvA frequency, which corresponds to the extremal cross section of the Fermi surface perpendicular to the field direction, was analyzed by the band calculations. The experimental data agree well with the theory, indicating that the 5f electrons can be treated as itinerant ones. The experimental dHvA study for plutonium-based superconductors such as PuCoGa$$_5$$ are also desired but more challenging because the superconducting mixed state extremely weaken the dHvA amplitude.
