PROBLEM TO BE SOLVED: To provide a gas burner combustion device using a metal oxidation catalyst that performs flameless low-temperature combustion by using gaseous fuel at a low concentration and transfers radiant heat like far infrared radiation. SOLUTION: In a gas burner combustion device utilizing a metal oxidation catalyst comprising an automatic control part 140 regulating the quantity of fuel to control an automatic fuel regulating valve 125 and an air-regulating valve 115 regulating the quantity of air, a mixer 130 has a means mixing the supplied fuel with air. A gas burner 160 comprises a support radiating the heat burned by the metal oxidation catalyst, a protective net, a heat insulating means, the metal oxidation catalyst generating un-catalytic-reaction activation energy, a preheater having a heating layer, a honeycomb-shaped diffusion net and housing, and has a structure in which the fuel-air mixture supplied through a fuel-air mixture pipe 131 is sealed. The metal oxidation catalyst of the gas burner 160 is a diffusion type with platinum, palladium or rhodium evaporated to stainless steel having excellent durability.
