A capacitance type touch panel is provided which detects an input operation position with high accuracy without being affected by noise irrespective of the input operation position and the size of an input operation body. A method of detecting an input operation position in the capacitance type touch panel is also provided. When an input operation position is in between adjoining intersection points (m,n), voltage change levels R(m, n), which are less than a cutoff threshold value, of intersection points (m1, n1) on a side opposite to the input operation position are removed from calculation data for the input operation position. Thus, even if either of the adjoining intersection points (m,n) is designated as an intersection point (m0, n0) having a maximum value, the calculated input operation position does not largely change.
