Fermi surface of low carrier compound CeBi has been investigated by the acoustic dHvA measurement of ultrasonic waves. The Fermi surfaces observed in the ferromagnetic phase of CeBi consist of the hole surfaces β1, β2, β3 and β4 located at Γ point and the electron surfaces α, γ at X points. The angular variation of the dHvA frequencies in CeBi is reproduced by the result of the band calculation based on the p-f mixing effect.
