This production method includes: an application step of feeding a coating liquid for forming the functional thin film onto a principal surface of a glass sheet on which the ceramic shielding layer has been formed beforehand, so as to allow the coating liquid to flow in a predetermined direction on the principal surface; and a drying step of drying the fed coating liquid.
