1. A temperature sensor, comprising:
a first supporting film made of an electric insulation material;
a second supporting film made of an electric insulation material; and
a sensor element provided between the first supporting film and the second supporting film, wherein the sensor element includes:
a thermosensitive body having electric characteristics that change with temperature, and
a lead pattern that is provided on the first supporting film and is electrically connected to the thermosensitive body, the lead pattern including a first lead pattern and a second lead pattern that are bonded on a same plane of the first supporting film,
wherein the first supporting film and the second supporting film are disposed to face each other in a region where the thermosensitive body is provided,
the first supporting film includes a first conductive pad that supports the thermosensitive body and is electrically connected to the first lead pattern, and a second conductive pad electrically connected to the second lead pattern,
the second supporting film includes a third conductive pad on a surface of the second supporting film that faces the region where the thermosensitive body is provided, and
the first lead pattern and the second lead pattern are electrically connected through the third conductive pad electrically connected to the thermosensitive body.
