A combustion apparatus for an internal combustion engine including a glow plug includes a plug cover that surrounds a heat generating part of the glow plug, and a plug cover that penetrates in a direction perpendicular to the flow direction of the air flow so as to cover the inside of the plug cover and the inside of the plug cover. A combustion device for an internal combustion engine, characterized in that the plug cover is provided with a through hole that communicates with the inside of the combustion chamber. (2) An internal combustion engine comprising a fuel injection nozzle that injects fuel into an airflow formed in a combustion chamber, and a glow plug that heats the fuel injected by the fuel injection nozzle to promote combustion of the fuel. In the combustion device, a plug cover is provided that surrounds the heat generating part of the glow plug, and the air flow is arranged on a side of the plug cover located on the downstream side in the flow direction of the air flow with respect to the glow plug. A combustion device for an internal combustion engine, characterized in that a through hole is provided that penetrates in parallel with the direction and communicates between the inside of the plug cover and the inside of the combustion chamber.
