The nonwoven structure has an apparent density of from 0.05 to 0.60 g/cm3. Preferably, the cleaning member may further include a support, and the support and the nonwoven structure may be arranged in contact with one another. Preferably, the single fiber may be an electrospun fiber. A method for manufacturing a cleaning member includes: a step of performing spinning by electrospinning, and thereby forming a deposit of a single fiber; and a step of pressing the deposit, and thereby forming a nonwoven structure having an apparent density of from 0.05 to 0.60 g/cm3.
