1. A detector comprising:
a frame that is at least partially formed from metal;
electrodes arranged in a coordinate planar direction of an operating surface, the operating surface being at least partially in contact with the frame, the electrodes detecting a user operation that is an approach or contact of a body of a user toward or with the operating surface; and
a calculator that obtains a calculation coordinate by calculating an operation position of the user operation on the operating surface based on an electrostatic capacity change in each of the electrodes, wherein
the operating surface is divided into areas,
the calculator determines in which one of the areas on the operating surface the user operation is performed, and
the calculator converts the calculation coordinate to a correction coordinate by shifting the calculation coordinate toward a center position of one of the areas including one of the electrodes in which the electrostatic capacity change is the largest, thereby determining that the correction coordinate is an operation position of the user operation.
