To provide an infrared shielding layer-coated glass plate excellent in visible light transmittance and radiowave transmittance, having a low infrared transmittance, and applicable to a site where mechanical durability is required, such as a window glass plate for an automobile, and its production process. An infrared shielding layer-coated glass plate comprising a glass substrate and an infrared shielding layer having the following first layer and the following second layer adjacent to each other formed on the glass substrate (provided that the first layer is present on the glass substrate side), wherein the first layer is a layer with a thickness of from 0.2 to 2 mum, having such a structure that fine ITO particles with an average primary particle diameter of at most 100 nm are bound to one another by a metal oxide matrix containing silicon oxide and titanium oxide; and the second layer is a metal oxide layer with a thickness of from 0.02 to 0.3 mum, containing silicon oxide and titanium oxide.
