PURPOSE: To make ignition to solid fuel possible surely and quickly by a method wherein at a combustion part where solid fuel is accomodated and held to be burnt a ceramic heater is fixed and red-heated with electric current by the operation outside the combustion part and solid fuel in the combustion part is ignited.

CONSTITUTION: An ignitor 12 is composed of a nearly wooden spoon or guitarshaped ceramic heater in plane view and fixed on the upper surface of a heat insulating and retaining layer 21 placed on the top surface of a wear plate 2. As the electrode parts 13, 13 of the heater are located at the outside of a combustion chamber 4 surrounded and formed by a cylindrical body 3, the electrode parts are prevented from being exposed directly to a high temp. atmosphere formed at the combustion time of solid fuel such as oil coke etc. Ignition is able to be carried out by only an power supplying operation from the outside of a device and an ignition operation is simple and the solid fuel is able to be surely ignited with no fear of combustion failure.
