description	PROBLEM TO BE SOLVED: To obtain measurement output stable against fluctuation of ambient temperature, relating to a displacement detection device comprising a tank circuit and a transmission circuit. SOLUTION: This device comprises a seef-exited LC oscillation circuit 1 which oscillates with a tank circuit 2, comprising of parallel connection of capacitors 21, 22 and a coil 23, as output load. And, a displacement detecting secondary coil 24, which is displaced relatively to a primary coil 23 while engaged with a displacement detecting body and made a closed circuit by a load resistance 242 of the value matching to the output impedance of the oscillation circuit 1, is electromagnetic-coupled to the primary coil 23 for providing in coaxial manner, and the inductive voltage of the primary coil 23 is made output voltage VDC.
