A manufacturing method of a glass article having an organic film, comprising: a step of 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 a plurality of voids are arrayed, on the first main surface, and to form a plurality of internal void arrays, each including a void or two or more voids arrayed from the in-plane void region to the second main surface, in the glass plate; a step of depositing the organic film on the first main surface of the glass plate; and a step of irradiating and scanning the first main surface of the glass plate, on which the organic film was deposited, with a laser light of a second laser that is different from the first laser, along the in-plane void region or a neighborhood of the in-plane void region, to separate one glass article or two or more glass articles from the glass plate along the in-plane void region, wherein, in the step, the first main surface is irradiated with the laser light of the second laser so that when a central portion of a surface of the organic film of the separated glass article on the first main surface side is MC, and a point in an end face of the glass article in a top view is MP, wherein in a case where the glass article has an approximately polygonal shape, MP is a point in the end face other than intersection portions of two adjacent sides of a polygon, at the point MP, a count number for fluorine and a count number for silicon obtained by an X-ray photoelectron spectroscopy are I MP and I MP (Si), respectively, and R MP is a ratio of the count number I MP to the count number I MP (Si), and at the central portion MC, a count number for fluorine and a count number for silicon obtained by the X-ray photoelectron spectroscopy are I MC and I MC (Si), respectively, and R MC is a ratio of the count number I MC to the count number I MC (Si), a ratio of the ratio R MP to the ratio R MC is 0.3 or more. a step of 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 a plurality of voids are arrayed, on the first main surface, and to form a plurality of internal void arrays, each including a void or two or more voids arrayed from the in-plane void region to the second main surface, in the glass plate; a step of depositing the organic film on the first main surface of the glass plate; and a step of irradiating and scanning the first main surface of the glass plate, on which the organic film was deposited, with a laser light of a second laser that is different from the first laser, along the in-plane void region or a neighborhood of the in-plane void region, to separate one glass article or two or more glass articles from the glass plate along the in-plane void region, wherein, in the step, the first main surface is irradiated with the laser light of the second laser so that when a central portion of a surface of the organic film of the separated glass article on the first main surface side is MC, and a point in an end face of the glass article in a top view is MP, wherein in a case where the glass article has an approximately polygonal shape, MP is a point in the end face other than intersection portions of two adjacent sides of a polygon, at the point MP, a count number for fluorine and a count number for silicon obtained by an X-ray photoelectron spectroscopy are I MP and I MP (Si), respectively, and R MP is a ratio of the count number I MP to the count number I MP (Si), and at the central portion MC, a count number for fluorine and a count number for silicon obtained by the X-ray photoelectron spectroscopy are I MC and I MC (Si), respectively, and R MC is a ratio of the count number I MC to the count number I MC (Si), a ratio of the ratio R MP to the ratio R MC is 0.3 or more.
