Claim 7:
8. The electrostatic input apparatus according to claim 1, wherein the operation determining unit calculates a ratio of a maximum value to a minimum value of the difference values at the coordinates on the circumference of the circle, wherein, if the ratio is higher than a third predetermined ratio and an angle between a first line segment connecting the barycentric coordinates and coordinates of the maximum value and a second line segment connecting the barycentric coordinates and coordinates of the minimum value is larger than π/4[rad] and smaller than 3π/4[rad] or larger than 5π/4[rad] and smaller than 7π/4[rad], the operation determining unit determines that the input operation using two or more fingers has been performed.
