The pair of side wall members 10, 10 envelops almost the entire length of the outer portion in the longitudinal direction between the rectangular metal mesh 4 and the burner body 2, and protrudes downward by a predetermined length beyond the rectangular metal mesh 4. The cooling air is prevented from flowing into the combustion surface of the combustion plate 3 and the exhaust gas is discharged through the rectangular metal mesh 4.
The side wall member 10 is in contact with the outside of the wire mesh holding member 5 to prevent gas flow between the side wall member 10 and the wire mesh holding member 5.

The side wall member 10 is made of a metal plate and formed into an L-shaped angle member, one of which is an attachment portion 10a that is attached to the flange portion of the burner body 2, and the other is a rectangular combustion plate 3 and the wire mesh holding member. 5 is a side wall portion 10 b that covers the outside of 5.
