METHOD OF PRODUCING SUBSTRATE WITH HEAT RAY SHIELDING FILM, AND METHOD OF PRODUCING ARTICLE INCLUDING ELECTRICALLY CONDUCTIVE OXIDE

PROBLEM TO BE SOLVED: To provide a method of producing a substrate with a heat ray shielding film in which at least heat ray shielding capability by electrically conductive oxide is not deteriorated by heat treatment without requiring special apparatuses for controlling an atmosphere. SOLUTION: In a substrate with a heat ray shielding film comprising a glass plate 1 as a substrate and an electrically conductive oxide-containing film 5 formed thereon, the film is heated in a state where the electrically conductive oxide is coated with an oxidation prevention material including silicon oxide and alkali metal oxide, so that at least one selected from insolation transmissivity and light transmissivity at a wavelength of 1,500 nm is reduced compared with the case before the heating.
