PURPOSE: A diesel particulate filter is provided to increase the soot mass limitation of the diesel particulate filter by precisely controlling a regenerating temperature controlling unit. CONSTITUTION: A main body(100), a plurality of partition walls, a plurality of channels, and a temperature sensor(200) are prepared. The partition walls are formed in the main body to the flowing direction of an exhaust gas. The channels are defined by the partition walls. The channels include front parts and rear parts. The temperature sensor is installed to the longitudinal direction of the rear side of a channel and measure the inside temperature of the sensor.
