Several SUSY models with partially composite Higgs bosons coupled to a strong sector have been proposed. Such strong dynamics would help to cause the electroweak symmetry breaking naturally. We focus on the compositeness of the Higgsinos in such models. We show that such a Higgsino compositeness can induce the characteristic decay branching fraction of the neutralinos: The decay branching fraction of the second lightest neutral Higgsino into the lightest neutral Higgsino with photon can be large due to a dipole interaction. We also discuss the Higgsino dark matter feature: The annihilation cross section into γZ can be large. This talk is based on arXiv:1311.6823.
