Isotope dependence of charge radii, i.e., isotope shifts, obtained by the Skyrme Hartree-Fock, the relativistic mean-field, and the relativistic Hartree-Fock calculations are compared. The tensor interaction plays a crucial role to reproduce the "kink" behaviour, irregularity of isotope shifts at the neutron magic number; thus in the non-relativisistic calculation, the "kink" behaviour at neutron magic numbers is reproduced well if the spin-orbit interaction is considered properly, where the isoscalar strength of the spin-orbit interaction and the isovector one need not be different. The symmetry energy is also important to reproduce the kink.
