PROBLEM TO BE SOLVED: To provide a portable combustion apparatus wherein heat of a burner in use is suppressed from being transmitted to the side of a gas flow rate adjuster, and combustion efficiency is improved. SOLUTION: A portable combustion apparatus comprises the gas flow rate adjuster 2 that includes a fuel gas injection nozzle 6 and is mounted on a gas bomb 1, a burner 5 that includes a plurality of mixed gas injecting frame hole 51, and a mixed gas supply pipe 3 for communicating the gas flow rate adjuster 2 and the burner 5. In the combustion apparatus, a closed chamber 10 is formed between thew adjuster 2 and the burner 5 for interrupting the injection nozzle 6 and a lower end opening 3b of the mixed gas supply pipe 3 from the atmosphere, and an air introduction hole 30 is formed at an upper portion separated from the fuel gas injection nozzle 6 in the closed chamber 10.
