Abstract
A shredded tobacco leaf pellet is composed of tobacco leaf shreds bound together with a resin binder while retaining air permeability. The shredded tobacco leaf pellet is produced by applying a polyol and a polyisocyanate to tobacco leaf shreds and then reacting the polyol and polyisocyanate to each other, whereby the tobacco leaf shreds are bound together while retaining air permeability. The shredded tobacco leaf pellet may be used to provide a cigarette-like snuff by holding the shredded tobacco leaf pellet within a cigarette-shaped hollow cylindrical member made of paper or a plastic material.
