The present invention relates to a metal fiber, in which frictional force between metal fibers, entanglement and processability are improved, a metal fiber yarn and a fabric including the same, a method for preparing the fabric and a use thereof. According to the present invention, there is provided a metal fiber having concave-convex patterns formed at intervals of 0.3-50mm in a longitudinal direction of the metal fiber; a metal fiber yarn including a metal fiber having concave-convex patterns formed at intervals of 0.3-50mm in a longitudinal direction of the metal fiber and drawn and the metal fiber yarn has a length of 0.45 m to 10.0m per gram; a fabric prepared from the metal fiber yarn; a method for preparing a fabric, including forming concave-convex patterns in a metal fiber at intervals of 0.3-50mm in a longitudinal direction of the metal fiber, forming a metal fiber yarn having a length of 0.45-10.0mm per gram by using the metal fiber in which the concave-convex patterns are formed, and weaving the metal fiber yarn into a fabric; and a filter material and a burner material made of the fabric. The metal fibers having the concave-convex patterns formed at regular intervals in the longitudinal direction have the improved frictional force between the metal fibers and processability due to the concave-convex patterns on the metal fibers and thus, a metal fiber yarn can be easily made with the metal fiber of the present invention. Further, the metal fiber yarn including the metal fibers maintains its form stably because metal fibers are not released. Also, the metal fiber yarn has a plurality of uniform and fine pores.
