ABSTRACT:
A gas component detector having a gas component detecting element made of sintered metal oxide for indicating an electrical resistance according to the components of a gas to be detected. A pair of electrodes transmit the electrical resistance indicated by the gas component detecting element and a ceramic tube has through-holes into which said pair of electrodes are inserted. The ceramic tube has a cylindrical ceramic heater which is prepared by having a piece of wet ceramic sheet on which a print pattern is formed with metal paste for forming a heat generator wound on and bonded to the outer wall of the ceramic tube before sintering. The heater is then sintered to be integral with the ceramic tube.
