In the tape winding device according to the first aspect, since each of the plurality of wires is positioned by passing through the wire passage hole, the wire is pushed by the tape tension in the direction in which the tape is wound. However, each wire does not deviate greatly. Therefore, it is possible to stably wind the tape around the outer periphery of the plurality of wires while maintaining the plurality of wires in a desired arrangement (for example, in a state of being linearly arranged in a line). In addition, it is preferable that the arrangement of the wire passage holes is appropriately offset in a direction opposite to a winding direction of the tape in consideration of a force received from the tape. Further, the wire passage hole has an advantage that the wire can be easily hooked in a tape winding preparation stage.
