PURPOSE:To improve the activity and durability of catalyst by supporting the catalyst onto the alumina layer formed onto the oxide layer formed at the catalyst supporting part in a combustion chamber. CONSTITUTION:An Ni-Cr-Al layer 2 as oxide layer is formed through metallization onto the surface part of the heater part of a glow plug 1, and a ZrO2 layer 3 as oxide layer added with Cu2O in 5wt% is formed through metallization onto the above-described oxide layer, and the product is immersed into alumina slurry and then dried and baked, and an alumina layer 4 is formed. Then, the glow plug is immersed into diammine dinitro platinum solution, and then dried and baked, and then the glow plug is immersed into rhodium chloride solution, and then dried and baked, and the glow plug activated as catalyst can be obtained. The activity of the catalyst can be improved markedly, and also the durability can be improved. |
