To provide a hydrogen and oxygen mixed gas combustion burner capable of effectively heating a container for cooking food and drink by preventing formation of a nucleus of a spark from a combustion spark of hydrogen and oxygen mixed gas, lowering temperature, and enlarging combustion volume.

The combustion burner includes a body part 11 which is airtightly connected to a gas line L supplying hydrogen and oxygen mixed gas while preventing external oxygen from flowing in and is formed in a generally cylindrical shape; a combustion part 12 whose inclined surface is formed in a rim shape along an upper edge of the body part 11; a plurality of flame holes 13 formed at regular intervals along the inclined surface of the combustion part; and a distribution part formed in the inside the body part 11 and distributing hydrogen and oxygen mixed gas flowing in through the gas line L to the flame holes 13.
