We calculate the sigma or f0(600) meson scalar form factor, i.e., its interaction with a scalar source. We make use of the knowledge that the sigma meson appears as a pole in pion-pion scattering. NLO Chiral lagrangians are used to calculate the interaction. Knowing the scalar form factor, we try to determine the scalar radius of the sigma meson.
