PROBLEM TO BE SOLVED: To develop a combustion device free from occurrence of white smoke even when a fire is extinguished immediately after ignition, as an embodiment improving the combustion device of a type where liquid fuel is evaporated in an evaporation chamber, and an evaporated gas is delivered to a combustion portion to be burnt. SOLUTION: An auxiliary heater 30 is mounted on a burner port base 36 by means of four screws 22. The auxiliary heater 30 is kept into contact with conductive wire introduction cylindrical portions 65, 66 and resistant columns 67, 68, and these parts are heated before ignition. The combustion gas is partially collided with the conductive wire introduction cylindrical portions 65, 66 and the resistant columns 67, 68, but the heat of the fuel gas is not drawn by the resistant columns 67, 68 as the conductive wire introduction cylindrical portions 65, 66 and the resistant columns 67, 68 are heated by the auxiliary heater 30. As the parts of the conductive wire introduction cylindrical portions 65, 66 and the resistant columns 67, 68 are intensively heated, reliquefaction is not found even when the fuel gas stagnates at the parts.
