Provided is a wood cement board that has a pattern of acute-angled and
deep recesses and projections on its surface, and that tends not to cause
cracking during a hardening and curing process, a drying process, a
transportation process and so on. The wood cement board has a pattern of
recesses and projections on its surface, in which the distance from the
apex of the projections to the rear face is 9 mm or more, and the
distance from the apex of the projections to the base point of the
recesses is 2 mm or more, and is equal to or less than half the distance
from the apex of the projections to the rear face. The average specific
gravity of the wood cement board as a whole, and the specific gravities
of the projections and the recesses are each 1.1 or more, and the
difference between the specific gravity of the projections and the
specific gravity of the recesses is less than 0.1.
