Zusammenfassung:PROBLEM TO BE SOLVED: To obtain an optical reflective member made of a thermoplastic resin having an optical reflective surface of superior specular reflection. SOLUTION: This optical reflecting member 10, made of a thermoplastic resin, has a rectangular planar optical reflecting surface 13 surrounded by a projecting part 12, a hollow part 14 is formed in the part of an optical reflecting member 11 constituting the entire region of the optical reflective surface 13, by introducing a pressurized fluid and a hollow part 14A extended from the part of the optical reflecting member constituting the entire region of the optical reflective surface is formed in a part of the part of the optical reflecting member constituting the projecting part 12.
