    摘要： An adhesion preventing member 21 formed in a substantially circular-cylindrical shape is provided in an exhaust pipe 2. Urea water injected from an injection nozzle 6 is introduced into an inner peripheral side of the adhesion preventing member 21 through an opening portion 21a, and hence adhesion of the urea water to an inner peripheral surface 2a of the exhaust pipe 2 is inhibited. In the adhesion preventing member 21, there are provided five dispersion members 22 each having a plurality of through-holes 22a and urea water is dispersed in the exhaust pipe 2 by flowing through through-holes 22a. The adhesion preventing member 21 and the dispersion members 22 are arranged at a part spaced apart from the inner peripheral surface 2a of the exhaust pipe 2, that is, at a part which is heated to high temperature in the exhaust pipe 2.

    摘要： A method of fabricating a substrate (1) used for purifying an exhaust gas is provided. This method comprises the step of transforming a pre-mold (10) having a first end, a second end, a plurality of partition walls (4) extending between the first end and the second end, the first transforming step for transforming the end portions of the partition walls (4) at the first end in such a manner that the ends of the partition walls (4) defining one of two adjacent passages (2,3) at the first end of the pre-mold (10) are collected toward the center of a corresponding passage and connected to each other, and the second transforming step for transforming the ends of the partition walls (4) at the first end in such a manner that the end surfaces of the partition walls (4) at the first end are depressed toward the center of each of the end surfaces.
