Abstract
A fiber structure manufacturing apparatus including: an accumulation portion that accumulates a material containing a resin and a fiber in air to generate a fiber web; a transport portion that transports the generated fiber web in a transport direction; and a heating and pressurizing portion that pressurizes the transported fiber web with a heated lower flat plate and an upper flat plate to melt the resin, in which a liquid absorbent having a first region where pressurization by the heating and pressurizing portion is performed the predetermined number of times and a second region where the pressurization is performed more than a predetermined number of times is formed by alternately repeating transport at a predetermined pitch shorter than a length of the flat plate in the transport direction by the transport portion and the pressurization.
