Abstract
A touch panel includes: a lower electrode substrate that includes: a first substrate surface; a first conductive film on the first substrate surface; and four electrodes on the first substrate surface; an upper electrode substrate that includes: a second substrate surface; a second conductive film formed on the second substrate surface and facing the first conductive film; an insulating layer formed on the second conductive film; and a conductive layer formed on the insulating layer, and a control unit that applies voltage to the electrodes and that detects a contact position at which the upper electrode substrate comes into contact with the lower electrode substrate by using an electric charge which is moved from the lower electrode substrate to the upper electrode substrate by the contact.
