The present invention provides a method for producing an absorbent sheet containing absorbent resins, hydrophilic fibers, and hydrophobic fibers, comprising: a dehydration step of dehydrating the absorbent resins and the hydrophilic fibers from a state of being in contact with each other and containing water to obtain composite compositions and a sheet-forming step of forming a sheet of the composite compositions and the hydrophobic fibers by heating while bringing the composite compositions and the hydrophobic fibers into contact with each other.
