The invention discloses a tool electrode and a method for machining a deep hole narrow groove by using the same. The method comprises the following steps of preparation work before formal machining: afixture for clamping a to-be-machined shaft, the tool electrode and the to-be-machined shaft are mounted and aligned; and formal machining: rough machining is performed on the to-be-machined shaft according to electric machining parameters set by a system, and a rough deep hole narrow groove is obtained; semi-finishing is performed on the rough deep hole narrow groove according to the actual dimensions of the rough deep hole narrow groove, and a semi-finished deep hole narrow groove is obtained; and semi-finishing is performed on the semi-finished deep hole narrow groove according to the actual dimensions of the semi-finished deep hole narrow groove, and the deep hole narrow groove is obtained. By the aid of the method for machining the deep hole narrow groove, repeated out-of-tolerance requirement bill dealing r
