Magnetoresistance and de Haas-van Alphen (dHvA) effect were studied to investigate Fermi surface topology in LaRu$$_2$$Al$$_{10}$$. From the positive magnetoresistance in a wide angular region, this compound is regarded as a compensated metal. On the other hand, dHvA measurement shows several Fermi surface branches with a cyclotron effective mass close to the electron rest mass. The Fermi surface topology was well explained by the band calculations.
