To provide a physical quantity distribution detector capable of increasing the resolution of physical quantity distribution.

The physical quantity distribution detector includes a conductive polymer fiber arrangement texture 10, comprising an arrangement 11 of conductive polymer fibers extending parallel to each other and an arrangement 12 of conductive polymer fibers, extending parallel to each other in a direction of crossing the arrangement 11; an energizing section 20 in electrical conduction to each conductive polymer fiber; an electrical characteristic detection sections 30 for each of the conductive polymer fibers; and an operational section 40 sectioning the conductive polymer fiber arrangement texture 10 into n×m division regions, including a plurality of crossing regions to define physical quantity for each division region as a matrix constituent element, and applying a matrix operational expression to a detected the electrical characteristic value. When the physical quantities of the division region which is an arrangement of the conductive fibers crossing each other and which includes the arrangement 12 of one conductive polymer fiber, the operational section 40 energizes the arrangement 11 of the other conductive polymer fiber crossing the arrangement 12 of the one conductive polymer fiber and controls the energizing section 20 so that the sensitivity of the division region changes.
