The invention relates to a glass substrate. The manufacturing method of the glass substrate of this invention is equipped with: (I) the process of forming a through-hole (11) in plate-shaped glass (10), (II) using the resin composition which has photosensitivity to the light of predetermined wavelength λ1 The step of forming the resin layer (20) on one main surface of the plate-shaped glass ( 10 ), (III) irradiating the light U including the wavelength λ1 from the other main surface side of the plate-shaped glass (10) to make the resin layer ( 20) the step of exposing the part covering the through hole (11) to light, and (IV) the step of removing the part exposed to light in step (III) to form the resin through hole (21). The plate-shaped glass (10) protects the resin layer (20) from being exposed to the light U incident on the other main surface of the plate-shaped glass (10) in the process (III) so that the resin layer (20) is not exposed to light. Light U Effects. |
