<p><P>PROBLEM TO BE SOLVED: To provide a honeycomb structure and a honeycomb filter which enable direct measurement of a temperature, an oxygen concentration and the like of a honeycomb structure part since an insertion hole to which a sensor can be inserted is formed on an end face of the honeycomb structure, can easily perform temperature control of the honeycomb structure as a base material, and enable mounting of various sensors in accordance with applications of OBD measurement, measurement of an oxygen concentration, an NOx concentration and the like, facilitate canning, can improve the durability of various attached sensors, and in particular, can be preferably used in a DFP without soot leakage. <P>SOLUTION: The honeycomb structure is divided by a porous partition wall 3 and is formed of a plurality of cells 5 acting as a flow passage of a fluid. The insertion hole 9 to which the sensor can be inserted is formed on the end face of the honeycomb structure, and a breakage prevention means 17 is provided on the inner circumference or in the proximity of the insertion hole 9. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
