In the sintering process of step S40, it is preferable to perform the sintering process in an atmosphere of nitrogen, inert gas, or protective gas, because the problem of oxidation of the heating element 30 made of metal can be avoided during the sintering process. Meanwhile, based on the effect of improving the tightness and combination of the glass, the porous body 10 and the heating element 30, the sintering process is preferably carried out at a temperature of 300-800 ℃, and the holding time is controlled for 30-90 min.
