1. A glass article comprising, on a glass substrate, a carbon-added silicon oxide layer, a transparent conductive oxide layer, and a shielding layer in this order, wherein
an atomic-composition percentage ratio C/Si of carbon to silicon in the carbon-added silicon oxide layer is 0.1 or more and 0.5 or less,
a linear expansion coefficient ash of the shielding layer is 7.7×10−3/K or less,
the shielding layer contains a crystalline component and a pigment, and
a crystallinity value expressed by a Count Per Second (CPS) ratio of the crystalline component to the pigment in X-ray diffraction measurement data of the shielding layer is 7 or more and 33 or less.
 
12. A glass article comprising, on a glass substrate, a carbon-added silicon oxide layer, a transparent conductive oxide layer, and a shielding layer in this order, wherein
an atomic-composition percentage ratio C/Si of carbon to silicon in the carbon-added silicon oxide layer is 0.1 or more and 0.5 or less,
a linear expansion coefficient ash of the shielding layer is 7.7×10−3/K or less,
the shielding layer contains a crystalline component and a pigment, and
a ratio of the C/Si of the carbon-added silicon oxide layer, to a crystallinity value expressed by a Count Per Second (CPS) ratio of the crystalline component to the pigment in X-ray diffraction measurement data of the shielding layer is 0.005 or more and 0.04 or less.
