1. A carbon nanotube-resin composite comprising:
a carbon nanotube assembled wire including a plurality of carbon nanotubes; and
a resin, wherein
the carbon nanotubes include a tube portion having a tubular shape and at least one cone portion having a conical shape that expands continuously in diameter from at least one end of the tube portion,
in the carbon nanotube assembled wire, the carbon nanotubes are oriented at a degree of orientation of 0.9 or more and 1 or less,
the carbon nanotube resin composite includes a plurality of the carbon nanotube assembled wires,
the plurality of the carbon nanotube assembled wires are oriented and bundled in a direction along a longitudinal direction of each of the plurality of carbon nanotube assembled wires, and
in the carbon nanotube resin composite, the resin is present between the plurality of the carbon nanotube assembled wires.
