Sumario:In this proceeding, the studies of the spin and parity numbers of the Higgs boson with the data collected by the ATLAS experiment are presented. The results include those from the individual channels, i.e. $H\rightarrow \gamma\gamma$, $H\rightarrow ZZ^{*}\rightarrow 4l$ and $H\rightarrow WW^{*} \rightarrow lvlv$ as well as the combination of them. The data are compatible with the Standard Model $J^{P} = 0^{+}$ and some specific models $J^{p} = 0^{-1}$, $1^{-}$, $1^{+}$, $2^{+}$ are excluded at the confidence levels above 97.8$\%$. Thus, the data provide the evidence for the spin-0 and CP-even nature of the Higgs boson.
