Method for producing glass sheet and glass sheet

A method for producing a coated glass sheet, produced by applying a functional liquid for providing a function to a glass sheet, to at least one face of the glass sheet, comprising:

• a first step of supplying the functional liquid to an ejection portion having a nozzle that ejects the functional liquid toward the glass sheet;
• and
• a second step of applying the functional liquid to a face of the glass sheet while moving the glass sheet relative to the ejection portion in a fixed state such that the functional liquid ejected from the nozzle is deposited on the face of the glass sheet;
• wherein a tube member that transports the functional liquid is connected to the ejection portion, and the tube member is made of a soft material,
• wherein the functional liquid is supplied by the tube member to the ejection portion in the first step,
• wherein an application line formed in the second step, the application line being on the face of the glass sheet along a region to which the functional liquid was ejected,
• wherein a coating formed, after the second step, by having the deposited functional liquid spread on the face of the glass sheet and along a direction from the application line, thereby covering a portion of the face of the glass sheet,
• wherein the formed coating in a vicinity within 1.2 mm of the application line in the direction includes positions each having a local maximum of a coating thickness,
• wherein the positions include a nearest position to the application line and another position different from the nearest position, and
• wherein the formed coating in the vicinity within 1.2 mm of the application line in the direction is such that a difference between local maximum of the coating thickness at the another position and local minimum of the coating thickness at an adjacent position to the another position is 0.3 μm or less.
