1. A fiber body manufacturing apparatus comprising:
a first transport belt on which a material containing fibers and starch for binding the fibers is accumulated;
an accumulating section that faces the first transport belt and forms a web by accumulating the material on the first transport belt by a dry method;
a transport section that includes a second transport belt disposed downstream in a transport direction of the web relative to the first transport belt, the transport section transporting the web by peeling off a first surface of the web from the first transport belt, and by bringing a second surface of the web, which is a surface opposite to the first surface peeled off from the first transport belt, into contact with the second transport belt;
a water-applying section that is disposed below the second transport belt so as to apply water toward the first surface of the web while the web is transported between the water-apply section and the second transport belt, the water-applying section applying the water toward the first surface of the web while the web is in contact with the second transport belt so that a second side surface side of the web is transported with a weaker adhesive force than a first surface side of the web thereby suppressing sticking of the web to the second transport belt; and
a pressurizing section that is disposed downstream in the transport direction of the web relative to the transport section, and pressurizes the web to which the water is applied and which is peeled off from the second transport belt.
