    Abstract: A ceramic formed body extrusion method for forming a ceramic formed body having a wall-shaped or plate-shaped formed portion by using an extrusion die provided with a slit for extrusion of a ceramic formed body from a raw material for forming, the slit including a slit former stage unit located on an upstream side in an extrusion direction in the extrusion and a slit latter stage unit located on a downstream side in the extrusion direction, the slit latter stage unit having a width of three to 27 times a width of the slit former stage unit, and by extruding a raw material containing a first particle having an aspect ratio of two or more and less than 300 such that the raw material passes though the slit former stage unit of the extrusion die and then passes through the slit latter stage unit.

    Abstract: A plugged honeycomb structure includes: a pillar-shaped honeycomb substrate having a partition wall base material that defines a plurality of cells serving as a through channel of fluid; a plugging portion disposed at open ends of predetermined cells at an inflow-side end face of fluid and at open ends of residual cells at an outflow-side end face of fluid; and a porous trapping layer disposed at least at a surface of the partition wall base material of the residual cells. The partition wall base material is formed by a base material porous body including cordierite as a main phase, the trapping layer is formed by a trapping layer porous body including cordierite as a main phase, and a part of the trapping layer penetrating into pores formed at the partition wall base material has a thickness of 0 to 20 μm.
