Abstract
A pressing detector and an electronic device that properly corrects an integrated value at any timing. An electronic writing instrument includes a housing, an operation unit, and a pressing detector, which includes a plurality of electrodes, a piezoelectric film, a base material, a strain resistive element, a base material, a ground electrode, and a circuit including a detection unit. When an operation surface is displaced due to pressing or release of pressing by an operator, a resistance value of the strain resistive element changes. As a result, the strain resistive element performs an output according to an amount of displacement of the operation surface. The detection unit can thus correct the integrated value by the output of the strain resistive element. Therefore, the pressing detector can properly correct the integrated value at any timing.
