PROBLEM TO BE SOLVED : To provide spatter electrodes for radioactive gas fixing processor whose manufacturing lead time is short and which can efficiently fix radioactive gas and a manufacturing method thereof. SOLUTION : In manufacturing spatter electrodes 12A and 12B for radioactive gas fixing processor, the following manufacturing method is applied. A composite metal layer 32 is formed around the circumference of a cooling tube of stainless steel 33a constituting the spatter electrodes 12A and 12B by : 1. coating mixed particles 45 with nickel particles of transition metal and yttrium particles of rare earth metal with a spray gun 41 of non-melt coating process; or 2. coating at the same location nickel particles of transition metal 45a and yttrium particles of rare earth metal 45b with individual spray guns 41a and 41b of non-melt coating process.
