A splice for gathering ends of an electrical wire bundle, capable of maintaining a welded portion at the center in a cap member regardless of the number of wires in the electrical wire bundle; protecting the welded portion from vibrations and impacts; and of being versatile so as to be used in multiple wire bundles. The splice includes: an electrical wire portion (10) having a wire core splice portion (14) in which wire cores (13) are welded together; a cushioning member (20) covering an outer circumferential face of the electrical wire portion (10); a protective cap (30) accommodating an end portion of the electrical wire portion (10) and fixes the electrical wire portion (10) via the wire core splice portion (14); and a cover tape (40) wound around the protective cap (30), a portion of the cushioning member (20) exposed from the protective cap (30), and the electrical wire bundle.
