A channel type micro combustor having a gradually expanded cross section comprises a channel type combustion chamber(1). The channel type combustion chamber has a channel cross section gradually increased from an inlet(11), through which air mixed with fuel is supplied, to an outlet(12) through which combusted exhaust gas is discharged. The maximum size of a channel cross section of the inlet is determined to the extent that a flame plane(1a) does not backfire. The minimum size of a channel cross section of the outlet is determined to the extent that the flame plane is not scattered out of the combustion chamber.
