Provided are a drawing creation method, a wire harness manufacturing method, and a drawing creation device (201). A drawing (61) showing a wire harness (101) is created by the drawing creation method. The wire harness is configured with wires bundled together. The wire harness includes wire branch points (103, 105, 107, 109, 111, 113, 115, 117) and branch lines (119, 121, 123, 125, 127, 129, 131, 133, 135, 137, 139, 141, 143). The drawing is created based on information including following [1] to [3] and at least one of following [4] or [5]: [1] a path (5) of the wire harness in a movable body, [2] a distance between path branch points (7, 9, 11, 13, 15, 17, 19, 21) where the path branches, [3] a length from each path branch point to a corresponding connection target of the wire harness, [4] identification information of the connection target of the wire harness, [5] identification information of the connection target of each wire. The drawing reflects a distance between the wire branch points and a length of each branch line.
