Abstract: A pet-used ultraviolet-sterilizing comb comprises at least one ultraviolet sterilizing lamp and a comb. The comb is formed by a handle and a combing portion. The combing portion has an opening. The opening is installed with a plate. The plate is formed with a plurality of round tapered claws. The claws are arranged along a straight line. A tip of each claw is transparent to ultraviolet ray. The ultraviolet sterilizing lamp is assembled in the combing portion of the comb for generating the sterilizing ultraviolet ray. The ultraviolet ray transmits through the tips of the claws. When combing hairs of a pet, bacteria and parasites on the body of the pet can be removed at the same time by the pet-used ultraviolet-sterilizing comb.
