Abstract: An assembled wire has a substantially rectangular cross section, and is formed by assembling a plurality of strands. Each strand has a conductor portion and a strand insulating layer covering the conductor portion. At least a part of the assembled plurality of strands in the longitudinal direction is covered with an outer insulating layer. The strand is formed as follows. First, the strand insulating layer is coated on the outer periphery of the conductor portion. At this time, a large number of voids are formed in a resin constituting the strand insulating layer. From this state, the strand is formed, for example, by collapsing the strand insulating layer by heating and pressurizing. At this time, it is possible to uniformly collapse the strand insulating layer by crushing the internal voids. Therefore, the voids in the strand are crushed and flattened in the thickness direction of the strand insulating layer over the entire periphery.
