The object is to provide a burner capable of taking in sufficient primary air even though the size thereof is compact, and capable of being used as an all-primary air burner. A burner includes a mixing pipe to which a fuel gas and combustion air are supplied, a burner main body having a mixing chamber at a top end on a downstream side of the mixing pipe, and a burner head which is provided at an upper part of the burner main body while communicating with the mixing chamber and has first and second burner ports for ejecting mixed gas of the fuel gas and air for combustion mixed in the mixing chamber. The burner further includes an extension pipe in the burner main body protruding inside the mixing chamber being formed by extending the mixing pipe.
