ABSTRACT:
A heat insulating and shielding glass panel that is capable of maintaining heat shielding performance even if heat treatment is carried out during manufacture. The heat insulating and shielding glass panel 1 is comprised of a pair of glass plates 11 and 12 that are hermetically joined together at their outer peripheral edges via a sealing frame 13 that fluidizes at low temperature, such that respective one surfaces of the glass plates 11, 12 face each other and a hollow layer 14 is formed between the glass plates; and pillars 15 that are substantially cylindrical spacers that are inserted into the hollow layer 14 as atmospheric pressure supporting members and determine the gap between the glass plates 11 and 12. A low-emission transparent multilayer 17 having an emittance of not more than 0.1 is coated by sputtering on each of surfaces 11aand 12aof the respective glass plates 11 and 12 facing the hollow layer 14 so as to realize high heat insulation performance. The low-emission transparent multilayer 17 is comprised of ZnO layers 33 and 35 as dielectric layers separated from each other in the direction of film thickness by an SiNx layer 34 as an amorphous layer, and an Ag—Pd layer 32 as a metal layer containing Ag and Pd.
