Abstract
A manufacturing method of a glass substrate with a hole having a diameter ϕ, and with a thickness θincludes setting a thickness θof a glass plate that is to be processed; preparing a glass plate with the thickness θ, having first and second surfaces opposite to each other; forming one initial characteristic object or two or more initial characteristic objects in the glass plate by irradiating the glass plate with a laser from a side of the first surface of the glass plate, the initial characteristic object having a size of a diameter ϕon the first surface; and performing wet etching for the glass plate having the initial characteristic object, so that from the initial characteristic object a hole having the diameter ϕon the first surface is formed, and a thickness of the glass plate is adjusted from θto a target value of θ.
