Abstract：
Here we employ the extended chiral constituent quark model to investigate the five-quark components in the N^*(1535) resonance. The axial charge of N^*(1535) and the electromagnetic transition γ^* N→N^*(1535) are also analyzed. The results show that there may be sizable strangeness component in N^*(1535).
