Disclosed is solubilized collagen fiber ball: that is crimped and does not have fiber separation defects within which the amount of water content and the amount of hydrophilic organic solvent are evenly distributed and that dissolve instantly and uniformly when used. The fiber ball has a composition that may comprise 66 to 87 wt % solubilized collagen, 2 to 6 wt % buffer salt, 10 to 22 wt % water content, and a trace amount to 6 wt % residual hydrophilic organic solvent, and is 3 to 25 mm in diameter, weighs 3 to 20 mg, has an average fiber size of 3 to 10 dtx, and a length of 1 to 20 cm. The fiber ball, which has a wavy shape and comprises uniform bundles of solubilized collagen fibers formed in a spherical shape, may have a bulk density of 4.0 to 8.0 mg/cm3, and a swab diameter of 3 to 25 mm.
