1. A temperature sensor comprising:
a sensor element including a thermosensitive body and a pair of first electric wires that are electrically connected to the thermosensitive body;
a protective tube for accommodating the sensor element;
a filling body that lies between the protective tube and the sensor element inside the protective tube; and
a pair of second electric wires that are connected to the pair of first electric wires, respectively, the pair of second electric wires comprising insulation coverings that integrally cover core wires of the second electric wires, respectively, wherein:
the pair of first electric wires comprise first regions, second regions, and third regions,
the filling body comprises a first covering layer, the first covering layer covering the first regions of the pair of first electric wires in a bundle and covering the second regions individually, and
the second electric wires are separated from each other inside of the protective tube and a distance between the second electric wires is decreased continuously inside of the protective tube while the insulation coverings are in contact with each other outside of the protective tube.
