Heat chamfering apparatus and method

A heat chamfering apparatus comprising:

• a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel;
• and
• a heater heating the heated body,
• wherein the heated body comprises a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel,
• the cross-sectional area of the contact region is smaller than the cross-sectional area of the heated region,
• the contact region has a closest point located most adjacently to the glass panel and a farthest point located farthest from the glass panel, and
• the contact region comprises a first cross-section portion to which the closest point belongs and a second cross-section portion to which the farthest point belongs, divided by a perpendicular bisector of a line segment connecting the closest point and the farthest point, a cross-sectional area of the first cross-section portion being smaller than a cross-sectional area of the second cross-section portion.
