Abstract
A multicore cable includes an oil absorptive interposition, and a core disposed to surround the oil absorptive interposition and including electrical wires. The electrical wires are twisted together. In a cross-section perpendicular to a longitudinal direction of the core, the core has layers in which the electrical wires are arranged on circumferences, and an innermost layer of the layers is closest to the oil absorptive interposition. A twist pitch of the electrical wires in the innermost layer is greater than or equal to 0.45 times and less than 0.8 times a twist pitch of the electrical wires in an outermost layer of the layers.
