Provided are a touch panel having a novel structure that is capable of allowing lines through which electric signals contributing to the detection of a touched position to have a lower sheet resistance and that is capable of suppressing corrosion of the lines; and a display device provided with the touch panel. A touch panel includes: a substrate (18); lines (36a to 36g) formed on the substrate (18) so that electric signals that contribute to detection of a touched position flow through the lines; terminal portions (42a to 42g) formed with respect to the lines (36a to 36g) so that the terminal portions are connected to an outer circuit; and covering films (20, 48a to 48g) that cover the terminal portions (42a to 42g), wherein the lines (36a to 36g) and the terminal portions (42a to 42g) are formed with metal films, and at least a part of the covering films (20, 48a to 48g) are conductive films (48a to 48g) that have higher corrosion resistance than the terminal portions (42a to 42g).
