PROBLEM TO BE SOLVED: To provide a method for improving energy density on the surface of a photoreceptor (a solar power generator or a solar light water heater) by collecting the solar light. SOLUTION: A light collecting device is formed with a mirror plane having high light collectivity based on the principal of a parabola curve. An optimum angle of installation is achieved to the purpose or target of receiving the solar light. The issues of the achievement of high light collectivity, the follow-up to the direction of the sun and the installation at the optimum angle independent of an installation site can be solved. By using the mirror plane having high reflectivity, the device for highly utilizing solar light energy is achieved, the profitability of an energy utilizing device (a solar power generator or a solar light water heater) is improved, and the utilization of natural energy is further developed and spread.
