Abstract
A flame rod of a hot water apparatus is attached to a side wall part of a case that surrounds a combustion region such that an insulator part is positioned on a downstream side of a burner port plate of a burner in a combustion gas flow direction. A core wire part includes an extending part extending from the insulator part toward the burner port plate, and a tip-side part positioned closer to a tip of the core wire part than the extending part. In the combustion gas flow direction, the tip-side part of the core wire part is opposed to at least one of burner ports, and the extending part is not opposed to any of the burner ports.
