Method of manufacturing conductive porous ceramic tube
 A method of manufacturing a conductive porous ceramic tube including the steps of mixing a powder of La or a La compound, Mn or a Mn compound and Sr or a Sr compound; firing the resulting mixture at a temperature of 1000.degree.-1400.degree. C. and synthesizing the compound of La.sub.1-x Sr.sub.x MnO.sub.3 (where 0<x.ltoreq.0.5); grinding the compound of La.sub.1-x Sr.sub.x MnO.sub.3 to form a powder of 2 to 10 .mu.m in a mean particle diameter; kneading 100 parts by weight of the powder with the addition of an organic binder, water and 1 to 8 parts by weight of a pore-forming agent; forming the kneaded material into a molded tube; drying the molded tube and thereafter firing the molded tube; at a temperature of 1300.degree.-1600.degree. C.
