Yb₄Sb₃ is known to show a valence fluctuation state, which is considered to relate with the high temperature phase of Yb₄As₃. To clarify an electronic state of Yb₄Sb₃, we tried to grow its high-quality single crystal and measure the de Haas--van Alphen effect. The residual resistivity ratio of the obtained single crystal was 500 and five dHvA branches were detected. Their cyclotron effective masses were in the range from 1.8m₀ to 10m₀.
