Provided is a pressure distribution detecting device using electromagnetic coupling, the cost of which can be reduced by reducing the number of wirings, the reliability of which can be improved, and in which an extra space other than a detecting region can be reduced. The pressure distribution detecting device includes a plurality of driving side loop-shaped wirings (20), a plurality of detecting side loop-shaped wirings (30) arranged in a direction orthogonal to the wiring, a plurality of electromagnetic coupling portions (36) constituted so as to allow the wirings to be electromagnetically coupled with each other, a driving unit (40) for driving the plurality of driving side loop-shaped wirings, and a detecting unit (50) for detecting a variation in the degree of the electromagnetic coupling of the electromagnetic coupling portion (36) from the plurality of detecting side loop-shaped wirings (30). Further, the plurality of driving side loop-shaped wirings (20) and the plurality of detecting side loop-shaped wirings (30) have common ground lines (25, 35) which combine the adjacent lines between the adjacent loop-shaped wirings as ground lines. |
