Electromagnetic mean squared radii of Λ (1405) are evaluated in chiral unitary approach. In this approach we regard Λ (1405) as dynamically generated resonances in the octet meson and octet baryon scattering, and also as K^^-N bound state. Especially for the Λ (1405) as K^^-N bound state we obtain negative electric mean squared radius. With the small binding energy of Λ (1405) in the chiral unitary approach, our results imply that Λ (1405) has structure that K^- is widely spread around p.
