Abstract
A pillar-shaped honeycomb structural body includes a first end face and a second end face substantially parallel to each other; and a peripheral surface connecting the first end face and the second end face. The first end face and the second end face have similar peripheral shapes. A taper rate P satisfies 0<P≦ approximately 4%, the taper rate P being expressed by the formula (1), taper rate P(%)=(DD)/(2L)×100, wherein the maximum width of the first end face is D, the maximum width of the second end face is D, and the distance between the first end face and the second end face is L.
