PROBLEM TO BE SOLVED: To provide the condensing structure of sunlight which can easily carry out the attitude control of a heliostat even if a reflection panel which is not an elliptical mirror is used. SOLUTION: Since sunlight L from the heliostats A, 2A, 3A is reflected toward one intersection point in a plane view, the attitude control of the heliostats 1A, 2A, 3A is easily carried out. Three reflection panels 1B, 2B, 3B are arranged in a triangular form and a cylindrical condenser 9 is arranged in the center of the triangle. As a result, the reflection panels 1B, 2B, 3B are arranged in a state of being brought into contact with one another. When the reflection panels 1B, 2B, 3B are brought into close contact with one another, the angle of the sunlight incident on the cylindrical condenser 9 approaches perpendicularity to efficiently condense the light with a small loss.
