1. A compressed stranded conductor comprising:
a central stranded wire having a plurality of conductive strands which are twisted together; and
an outer circumferential stranded wire having a plurality of conductive strands which are twisted together at an outer circumference of the central stranded wire and disposed at the outer circumference of the central stranded wire as a layer, wherein
a composite stranded wire configured by the central stranded wire and the outer circumferential stranded wire is compressed, and an occupancy ratio of the composite stranded wire is 90.2% or more and 91.0% or less; and
the occupancy ratio is a rate of a value obtained by dividing a weight of the composite stranded wire after compression and cut into 1 meter by a specific gravity of a conductor material of the composite stranded wire, with respect to a value obtained by multiplying a square of a conductor radius of the composite stranded wire after compression by π.
