Classification: CPC G | IPC G

Claim 1:
2. The detector according to claim 1, wherein
the operating surface has an X-Y plane in which an x-axis and a y-axis are orthogonal to each other and served as coordinate axes,
the calculator obtains an x-coordinate of the calculation coordinate from a first operational expression, the first operational expression weighting the electrostatic capacity change in accordance with a position of each of the electrodes in an x-axis direction on the X-Y plane, and
the calculator obtains a y-coordinate of the calculation coordinate from a second operational expression, the second operational expression weighting the electrostatic capacity change in accordance with a position of each of the electrodes in a y-axis direction on the X-Y plane.
