The purpose of the present invention is to provide low-chargeable fibers having biodegradability. The present inventors found that, when a specific amount of a specific phospholipid that is not known to have antistatic properties is added to a biodegradable polymer and the resulting mixture is formed into fibers having smooth surfaces, the fibers have low chargeability, and the present invention has been completed. The present invention provides fibers which have surfaces having an average porosity of less than 3%, and each of which comprises a biodegradable polymer containing a specific amount of a specific phospholipid. |
