Electrical resistivity ρ and magnetic susceptibility of sintered Ca_<1-x>Sr_xRuO_3 have been measured. The Weiss temperature changes sign at about x=0.5 in consistent with other studies. Temperature dependence of normalized ρ is almost identical for all the materials in the paramagnetic temperature range irrespective of the sign of magnetic interaction. The Rhodes-Wolfarth ratio is 1.3 for x=1. This ratio and the temperature dependence of ρ suggest that 4d-electrons in this system are in the intermediately localized state as in Ni. The sign of magnetic interaction is discussed in connection with the orthorhombic lattice distortion, and the antiferromagnetic interaction is attributed to this distortion.
