PROBLEM TO BE SOLVED: To provide a manufacturing method for a glass-sealed porous ceramic hollow thread effectively prevent deflection of the porous ceramic hollow thread penetrated through a support made of ceramic or the like from being generated by gravity force at heating of a glass material when glass sealing covering layers are provided at both end sides of the porous ceramic hollow thread penetrated through the support made of ceramic or the like. SOLUTION: When outer surfaces at both end sides of the porous ceramic hollow thread which keeps the support penetrated in the inner pipe part are coated with a glass material and calcination is performed to form the glass sealing covering layers, and both ends of the support projected from both ends of the porous ceramic hollow thread placed on the base, further a heavy weight substance is superposed on the base, and calcination of the glass material is performed in the bridge form that both ends of the support are fixed. Thereby, the glass sealing porous ceramic hollow thread is manufactured. COPYRIGHT: (C)2009,JPO&INPIT
