We succeeded in growing high-quality single crystals of V$$_{5}$$Si$$_{3}$$ with a high melting point of 2010 $$^{circ}$$C, and carried out the electrical resistivity, specific heat, magnetic susceptibility, and the de Haas-van Alphen measurements to clarify the electronic properties. The Fermi surface is small in volume and is well explained by the result of energy band calculations. The cyclotron mass is in the range from 5.3 to 0.2 $$m_0$$ ($$m_0$$: rest mass of an electron), consistent with the electronic specific heat coefficient $$gamma$$ = 9.7 mJ/(K$$^{2}$$$$cdot$$mol).
