    摘要： A honeycomb structure body is constituted of a circumferential region including the outermost circumference in a cross section of the honeycomb structure body which is perpendicular to an extending direction of cells, and a central region excluding the circumferential region. The circumferential region includes a specific circumferential region in which pressure loss with soot when an amount of the deposited soot is 4 g/L is higher than the pressure loss with soot of the central region as much as 15% or more and in which an open frontal area of the circumferential region is the same as or larger than an open frontal area of the central region. In the cross section of the honeycomb structure body, a ratio of an area of the specific circumferential region is 5% or more to a total area of the circumferential region and the central region.

    摘要： A support member (40) is provided on a cylindrical member (23) of an upstream cylinder (22). A connector portion (34C) of a first temperature detector (34) for detecting the temperature of exhaust gas flowing into an oxidation catalyst (25), a connector portion (35C) of a second temperature detector (35) for detecting the temperature of the exhaust gas flowing into a particulate matter removing filter (31), and a sensor portion (39A) of a pressure detector (39) for detecting the front and rear pressures of the particulate matter removing filter (31) are arranged to be mounted on this support member (40). Accordingly, the support member (40) is capable of supporting the connector portions (34C, 35C) of the temperature detectors (34, 35) and the sensor portion (39A) of the pressure detector (39) in one location in a concentrated manner, so that harnesses on a controller side can be easily connected thereto.
