The electron scattering on 3He nucleus is investigated using the Faddeev 3-body theory. The modified Faddeev equation is briefly introduced by extending 3-nucleon scattering. First we have analyzed elastic scattering and pd break-up process at NIKHEHF. For the 3N break-up process we will show some theoretical predictions. Using MT Bates' data the inclusive processes are studied with the response functions and the Coulomb sum rule. As a neighbor field of the study we will show pd radiative capture with the meson exchange currents.
