the film thickness of the zro 2 layer was varied at a pitch of 5 nm with the fixed film thickness values of 10 nm for the sio 2 and tio 2 layers fig1 is a graph showing the reflection color tone variation for the distance between the chromaticity coordinates d range of 3 5 or less corresponding to fig1 fig1 is a graph showing the variation of the distance between the chromaticity coordinates d of multiple glass observed when the film thickness of the tio 2 layer was varied at a pitch of 5 nm with the fixed film thickness values of 10 nm for the sio 2 and zro 2 layers fig1 is a graph showing the reflection color tone variation for the distance between the chromaticity coordinates d range of 3 5 or less corresponding to fig1 fig1 is a graph showing the variation of the distance between the chromaticity coordinates d of multiple glass observed when the film thickness of the zro 2 layer was varied at a pitch of 5 nm with the fixed film thickness values of 10 nm for the sio 2 and tio 2 layers and fig1 is a graph showing the reflection color tone variation for the distance between the chromaticity coordinates d range of 3 5 or less corresponding to fig1 when d is 3 5 or less even if the film thickness varies in the manufacture the color unevenness is not conspicuous which is preferable from the viewpoint of quality control it is apparent that the magnitude of d indicates the degree of the color 39 s inclination to vary and the present invention has.
