A false eyelash that is easily wearable and prevented from slippage and separation while in use includes an extremely thin base, bonding layer formed linearly on a surface of the base, a plurality of hair segments individually and separately adhered to the bonding layer, and an adhesive layer formed on an entire underside of the base. The base is formed into substantially a two-dimensional configuration or three-dimensional configuration that contours a curved shape of an eyelid to which the base is fitted. Since the base is formed into an extremely thin two-dimensional configuration or a three-dimensional configuration that contours a curved shape of the eyelid, it may be fitted tightly to the eyelid. The hair segments are firmly adhered to the bonding layer such that they remain linearly attached to the base, by which the false eyelash with the well-aligned hair segments can easily be fitted to the eyelid.
