The invention provides a heat reflecting glass plate with a six-layer coating excellent in optical characteristics and also in durability on a transparent glass plate. The coating consists of (1) a metal oxide film deposited on the glass surface, (2) a metal nitride or oxynitride film deposited on the oxide film, (3) a metal film of Ti, Zr, Ta, Cr, Ni-Cr or stainless steel deposited on the nitride or oxynitride film to a thickness of 30-150 Å, (4) a metal nitride or oxynitride film overlying the metal film, (5) a metal oxide film overlying the film (4) and (6) a film of an oxide or oxynitride of Si-Al, Si-Ti or a film of aluminum nitride or oxynitride deposited on the film (5) to a thickness greater than 300 Å. The metal for the oxide films (1) and (5) is Ti, Zr, Ta, Sn or Cr, and the metal for the nitride or oxynitride films (2) and (4) is Ti, Zr, Ta, Cr, Ni-Cr or stainless steel. Each of the oxide films (1) and (5) is 200-1000 Åin thickness, and each of the nitride or oxynitride films (2) and (4) is 300-200 Å in thickness. The heat reflecting glass plate is not lower than 30% in transmittance for visible light, not higher than 60% in transmittance for solar radiation and not higher than 20% in reflectance for visible light.
