A low density body such as a sheet, board or molding usable as a cushioning material, heat-insulating material, sound-absorbing material, filter, low density base paper or the like is provided. The low density body having a density of 0.05 to 0.45 g/cm.sup.3 is prepared by dewatering a slurry containing fine fibers having a bond-reinforcing factor of at least 0.15 and curled fibers having a wet curl factor of 0.4 to 1.0, and drying the resultant product.

Low density body

Finely divided fibrous cellulose particles having a high viscosity, suspension stability and water-retaining property are produced by suspending cellulose particles in water or an organic liquid, and subjecting the resultant cellulose particle slurry to a wet grinding procedure in a solid medium-agitation type grinder in which the cellulose particles are agitated and ground with solid medium particles, for example, glass beads, to an extent such that the cellulose particles are divided into fine fibrous cellulose particles having a water-retaining power WRP of 150% or more in accordance with an equation (I):
