A connection structure of a carbon nanotube wire includes a joint between the carbon nanotube wire and the connection target. For example, a connection structure of a carbon nanotube wire includes a carbon nanotube wire, and, a connection target to which the carbon nanotube wire is connected. The connection structure further includes a conducting wire with higher solder wettability than the carbon nanotube wire, a penetrating part of the conducting wire formed along a cross section having a component orthogonal to a longitudinal direction of the carbon nanotube wire, and solder that connects the carbon nanotube wire and the connection target. The solder penetrates the penetrating part formed along the conducting wire.
