Abstract: An in-vehicle system used in a getting-on-and-off authentication system includes: a reading unit provided in a vehicle to read identification information capable of identifying a person; a communication unit that transmits the identification information read by the reading unit to an external device outside the vehicle and receives retrieval result information retrieved on the basis of the identification information by the external device; and a getting-on-and-off authorization processor capable of executing a process of authorizing a getting on and off of a person specified by the identification information on the vehicle on the basis of the retrieval result information received by the communication unit.

Abstract: A communication electric wire (1) includes a twisted pair wire (10) having a pair of conductor core wires (11) spirally bundled together and a protection layer (20) formed from resin and cylindrically covering an outer circumference of the twisted pair wire (10). The twisted pair wire (10) contacts an inner face of the protection layer (20) to eliminate its relative movement with respect to the protection layer (20) in the direction orthogonal to the axial line of the communication electric wire (1). The protection layer (20) is configured to have a specific ratio of 1 or more. The specific ratio is a ratio (c/D) of a thickness (c) of a portion where the protection layer (20) having the smallest thickness in a cross section orthogonal to the axial line of the communication electric wire (1) to a distance (D) between centers of the pair of the conductor core wires (11).
