Abstract: A method for producing a glass article from a glass member including a glass substrate including a first main surface, a second main surface and an end face, and an irregular layer formed in at least one of main surfaces, includes forming an irregular layer having a glass transition point Tg which is equal to or lower than a glass transition point in a central part of the glass member in a thickness-direction sectional view and performing a heat treatment on the glass member so as to have an equilibrium viscosity in the central part of the glass member in thickness-direction sectional view of 1017 Pa·s or lower.
