According to the first invention of the present application, the hot plate 5 and the halogen lamp unit 2 are mounted on the top plate in a suspended state via a support ring, thereby assembling the halogen electric stove with the inside of the stove case and the top plate. By dividing the work into two parts, efficiency and simplification of the assembling work can be achieved. According to the second invention of the present application, the cooling air from the cooling air blower is passed through an air hole formed in the support ring to cool the top plate, thereby maintaining the top plate at a temperature at which there is no danger of burn. Due to the formation of the air holes, if water leaks to the top plate, the water flowing down from the air holes in the support ring causes short-circuiting of the terminals at the terminals of the halogen lamp unit in the halogen case due to poor insulation, and heat generation at the terminals. Although there is a danger, the waterproof cover made of a heat-resistant synthetic resin waterproofs the terminal portion of the halogen lamp, thereby preventing the failure due to the terminal short-circuit and the accident due to the heat generation of the terminal portion.
