PG1030+590 is a recently discovered nova-like eclipsing variable. Results of high-speed photoelectric photometry and UBVR light curves are presented. Using the model of cataclysmic variables, it is found its geometrical and physical parameters to be as follows: mass of the white dwarf component = 0.83 + or - 0.22 solar masses, radius of the late-type component = 0.35 + or - 0.06 solar masses, and orbital inclination = 81 + or - 2 deg.
