A touching apparatus and a touching detecting method thereof are provided. The touching detecting method is adapted for a touch panel. The touch panel has a plurality of touching rows and a plurality of touching columns. The touching detecting method includes: performing a mutual-capacitor touching detection and a self-capacitor touching detection alternatingly to the touch panel for obtaining a mutual-capacitor detection result and a self-capacitor detection result, respectively; and obtaining position information of at least one touch point on the touch panel by an operation based on the mutual-capacitor detection result and the self-capacitor detection result.
