The angular dependence of de Haas-van Alphen effect has been measured to reveal the electronic structure of filled skutterudite PrRuSb. The angular dependence of de Haas-van Alphen frequency of PrRuSb is in good agreement with that of LaRuSb. Compared with PrFeP, no anomalous enhancement of cyclotron effective mass has been observed in this system. This change of electronic structure is attributed to the difference in the hybridization strength, which is expected from the large difference in the lattice parameters.
