PROBLEM TO BE SOLVED: To provide a touch sensor capable of determining an operation kind without depending upon the number of touching fingers.SOLUTION: A touch tracer 13 for detecting a plurality of touch positions to an operation surface 12a to generate touch signals showing the touch positions, and a specific operation determination part 14 for determining whether to be a tracing operation or a pinch operation on the basis of a touch position signal are provided. The specific operation determination part 14 determines whether to be a tracing operation or a pinch operation through comparison between a position change amount per unit time of at least one touch position and a distance change amount per unit time between two touch positions including at least the one touch position when at least two touch signals are generated. |
