A stylus has a piezoelectric element support part to support and fix piezoelectric elements. The piezoelectric element support part is a regular polygonal body and its cross section orthogonal to the axis of the stylus is made a regular polygon. The piezoelectric elements are mounted on each side surface of the regular polygonal body, respectively. Sums and difference signals outputted from the piezoelectric elements are produced and a touch detection signal is generated based on the produced signals.
