A burner includes a partition wall that partitions a mixing chamber, which generates an air-fuel mixture, and a combustion chamber, which burns the air-fuel mixture. The partition wall includes a plurality of communication passages that communicate the mixing chamber with the combustion chamber. Further, a heating unit that heats the partition wall is attached to the partition wall. Such a structure heats the partition wall and a mesh with the heating unit and burns particulate matter deposited on the partition wall and the mesh.
