An ignition device that ignites a mixture including an oxidizer and fuel includes a heating element (1) that has a heat generation region (1a) generating formerly heat to a temperature above the ignition temperature of the mixture (Y) at a tip projected downward from an installation unit (100), a fuel holding unit (2) that encloses the heat generation region (1a), in which the heat generation region (1a) is installed inside thereof and has a through hole (2a) opened to an upper part thereof, and a surrounding wall (3) that forms a space (R) connected to the upper part of the through hole (2a) and has a flame ejection opening (3a) opened from the space (R) to the outside. According to the ignition device, an ignitability of the ignition device can be improved. |
