Abstract: A manufacturing method of a glass article having an organic film includes irradiating a first main surface of a glass plate having the first main surface and a second main surface, opposite each other, with a laser light of a first laser, to form an in-plane void region, in which voids are arrayed, on the first main surface, and internal void arrays, including voids arrayed from the in-plane void region to the second main surface, in the glass plate; depositing the organic film on the first main surface or the second main surface of the glass plate; and irradiating and scanning the first main surface or the second main surface, on which the organic film was deposited, with a laser light of a second laser, along the in-plane void region, to separate the glass article from the glass plate along the in-plane void region.
