The structure of ^4_ΣHe is analyzed within the frame of the [^3H+Σ^+]+[^3He+Σ^0] model. It is found that 1) the ^4_ΣHe hypernucleus with almost pure isospin 1/2 is bound mainly due to the constructive contribution from the ( t_Ν t_Σ) and (t_Ν t_Σ)(S_ΝS_Σ) terms of Σ-Ν interaction, and 2) the latter contribution is about twice larger than the former.
