<P>PROBLEM TO BE SOLVED: To provide a contact combustion type gas sensor which is comparatively easy to be manufactured and has high reliability, high sensitivity, and a long life, and a method for manufacturing the same. <P>SOLUTION: In the contact combustion type gas sensor including a detection element 1 and a reference element 2 in a pair thermally isolated from each other, the detection element 1 includes a reaction film 1a obtained by embedding a platinum system electrode wire 4 in thermistor ceramics 3a and mixing a reaction catalyst of detection gas on the surface of the thermistor ceramics 3a; the reference element 2 includes a non-reaction film 2a obtained by embedding the platinum system electrode wire 4 in the thermistor ceramics 3a, which does not contain the reaction catalyst of the detection gas on the surface thereof, and whose calorific capacity is equal to that of the reaction film 1a; and terminals 5 which are connected to the respective pieces of the electrode wire 4 in the detection element 1 and the reference element 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
