Abstract
A method for manufacturing a fiber absorber includes individuating preformed fibers, compressing the preformed fibers, housing the compressed fibers in a needle-punch processing case in which needle insertion holes are formed, and performing needle punching by inserting needles through the needle insertion holes from at least three directions having perpendicular relation to one another in the needle-punch processing case.
