Abstract
A method for producing a glass substrate according to the present invention includes the steps of: (I) forming a through hole () in a glass sheet (); (II) forming a resin layer () on a first principal surface of the glass sheet () using a resin composition sensitive to light having a predetermined wavelength λ; (III) photoexposing an area of the resin layer () that covers the through hole () by irradiating the area with light U having the wavelength λand applied from the direction of a second principal surface of the glass sheet (); and (IV) forming a through-resin hole () by removing the area photoexposed in the step (III). The glass sheet () protects the resin layer () from the light U so as to prevent the resin layer () from being photoexposed by beams of the light U that are incident on the second principal surface of the glass sheet () in the step (III).
