The Fermi surface topology of the layered perovskite Sr2RuO4 was investigated through the observation of angle-dependent magnetoresistance oscillation under a magnetic field up to 17 T at 1.5 K. A series of angles giving the resistance peaks, observed under a constant field above 5 T, can be assigned to the Fermi wave-number vector of both the α and β branches of the calculated Fermi surface.
