A heating device (90) partially heats a glass substrate (1) to be chamfered along with relative movement of the glass substrate (1). The heating device (90) is provided with a main heating part (10) and a peripheral heating part (20). The main heating part (10) heats the glass substrate (1) to a temperature near a softening point of glass. The peripheral heating part (20) heats the glass substrate (1) to a temperature lower than or equal to a strain point of glass. The main heating part (10) is arranged near a position to be chamfered. The peripheral heating part (20) is, in a direction perpendicular to the relative movement direction of the glass substrate (1), arranged adjacent to the main heating part (10), and arranged on a side farther from a position where the thermal processing is subjected to the glass substrate (1), than the main heating part (10).
