The touch panel of the present invention is a touch panel (1) that applies drive signals to drive electrodes (2) and carries out detection on the basis of the variation in the amount of charge that has been induced on detection electrodes (3), and is configured such that when drive signals are being applied to the drive electrodes, complementary signals having a different phase from the drive signals are applied to complementary electrodes (4), and the complimentary electrodes (4) are configured such that the amplitude (ΔVcm) of the complimentary signals satisfies the following formula: ΔVcm=−ΔVdr×(Cfo+Ccr)/Ccm.
