A touch panel controller of the invention is provided with a driving unit which drives drive lines and causes a linear sum signal based on charges accumulated in respective electrostatic capacitances to be output from a sense line, and a correction processing unit which corrects influence on a change in the electrostatic capacitances by a parasitic capacitance which exists in the sense line. Thereby, it is possible to provide the touch panel controller and an electronic device capable of performing estimation of an electrostatic capacitance value more correctly by correcting the influence of the parasitic capacitance which exists in the sense line. |
