Recently, barium-iridium silicide BaIrSi including Ir with 5d electron was discovered. This compound has noncentrosymmetric crystal structure and superconductivity appears below Tc=6K. To clarify the superconducting properties, we have measured the temperature dependence of the magnetic penetration depth in BaIrSi using muon spin rotation measurement at J-PARC. The structure of the superconducting gap and time reversal symmetry of Cooper pair will be discussed.
