<P>PROBLEM TO BE SOLVED: To provide a planar temperature detection sensor can accurately detect the temperature of an object to be temperature detected, by suppressing the influence due to heat generation from own components. Ž<P>SOLUTION: This planar temperature detecting sensor 10 includes a flat casing 10, comprising a detection side layer 11, a non-detection side layer 12 and a middle layer 13. A plurality of thermistor elements THs are installed radially, at prescribed intervals by using the center of a magnetic flux as a reference point, as viewed from a detection surface 111 side inside the casing 10. A wiring electrode 15, for connecting each thermistor element TH, is equipped with a first partial electrode 151 which extends in a direction orthogonal to the detection surface 111; namely, a parallel direction to a magnetic flux direction, and a second partial electrode 152 which extends, in parallel with the detection surface 111. The second partial electrode 152 is installed at a position separated from the thermistor element TH, at the side opposite to the detection side layer 11 via the thermistor element TH. The first partial electrode 151 connects the second partial electrode 152 to the thermistor element TH. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
