<p><P>PROBLEM TO BE SOLVED: To provide a long-life, mass-producible, high-sensitivity soot sensing structure. <P>SOLUTION: In a soot sensor having a precious metal structure sensing soot from strip conductor segments on an electrically insulated carrier 7, the strip conductor segments with the precious metal structure having the width of 5 to 100μm and being mutually spaced 5 to 100μm apart, the electrically insulated carrier 7 is of single crystal and a precious metal is crystallized on the surface of the single crystal, or the electrically insulated carrier 7 is of polycrystal and the precious metal is crystallized on the electrically insulated polycrystalline carrier 7. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
