• and
• a plurality of heat supply portions disposed on each of the side portions,
• wherein the side portions include a side portion disposed between outermost side portions,
• the plurality of heat supply portions are disposed directly on both of opposing surfaces of the side portion disposed between the outermost side portions,
• adjacent side portions adjacent to each other are disposed to face each other,
• each of the side portions includes a thermally conductive material,
• the thermally conductive material of each of the side portions overlaps the heat supply portions in a thickness direction of the side portions,
• a groove is defined by a depressed portion of the support portion from a surface of the support portion between the adjacent side portions, and
• a glass is allowed to be inserted into the groove between the adjacent side portions.
