An object of the present invention is to provide a honeycomb structured body with a catalyst supported thereon, which has an excellent converting performance of CO, HC, NOx and the like, as well as a low pressure loss, and the honeycomb structured body of the present invention is a honeycomb structured body comprising a pillar-shaped honeycomb member having a large number of cells longitudinally disposed in parallel with one another with a wall portion interposed therebetween and mainly comprising inorganic fibers that are integrally molded therein, wherein the cells are sealed at either one end; a catalyst is supported on the wall portion in an amount of 100 to 400 g per liter of volume of the honeycomb structured body; and the honeycomb member presents a pore distribution curve having three peaks in ranges of 0.005 to 0.03 µm, 1 to 15 µm, and 15 to 50 µm of a pore diameter in a pore distribution by mercury porosimetry, the pore distribution curve being drawn by plotting the pore diameter (µm) on an X-axis and a log differential pore volume (mL/g) on a Y-axis.
