PROBLEM TO BE SOLVED: To provide an induction type sensor being immune to any external effect, and requiring very small structural space. SOLUTION: This induction type sensor comprises at least two printed circuit boards 1, 2, wherein receiver pattern wires 1.1 are mounted on the first printed circuit board 1 while structural elements 2.1 of evaluation electronics for evaluating signals resulted from these receiver pattern wires 1.1 are provided on the second printed circuit board 2. Both of these printed circuit boards 1, 2 are sandwiched each other, and at least one of the structural elements 2.1 of evaluation electronics is stored between both of these printed circuit boards 1 and 2. Further a rotary detector composed of this inductive sensor is provided. COPYRIGHT: (C)2004,JPO&NCIPI
