Abstract: The invention relates to a temperature sensor (10) for a fluid pipe, in particular for a motor vehicle, this sensor (10) comprising a first part (20) comprising a flat surface (22) configured to be in contact with a fluid and on which is located a track (41) forming a thermosensitive element (40), this track (41) having a generally elongated shape and comprising opposite ends (41A, 41B) connected respectively to terminals (43) of the sensor (10) by electrical conductors (42) embedded in said body (15).
The invention also relates to a fluid pipe comprising such a sensor (10), a motor vehicle comprising such a sensor (10) or such a pipe and a method for manufacturing such a sensor (10).
