The burner head communicates with the mixing chamber and ejects the mixed gas of the fuel gas and air mixed in the mixing chamber. The burner head has a cylindrical shape and is provided right above the mixing chamber of the burner main body. The burner head has several first and second burner ports bored around almost an entire periphery of a side face thereof. The mixing pipe extends in a direction where the mixing pipe is crossed with an axis line of the burner head at substantially right angles to each other.

1 . A burner comprising:
 a burner main body having a mixing pipe to be supplied with a fuel gas and combustion air, and formed with a mixing chamber at a top end on a downstream side of the mixing pipe; and   a burner head provided at an upper part of the burner main body while communicating with the mixing chamber, and having burner ports for ejecting the mixed gas of the fuel gas and combustion air mixed in the mixing chamber,   wherein the burner head is in a cylindrical shape having a plurality of burner ports bored around an almost whole periphery of a side face thereof, and provided right above a mixing chamber of a burner main body; and   wherein the mixing pipe is provided to be directed in a direction where the mixing pipe is crossed with an axis line of the burner head at substantially right angles to each other.
