Abstract
A touch sensor (2) includes: a substrate (21); a net-shaped electrode (22) which is provided on the substrate (21) and includes conductive wires (221) arranged in a net form; and an outer edge wire (23) which is provided in at least a part of an outer edge of the net-shaped electrode (22) and is integrally formed with the net-shaped electrode. The conductive wire (221) includes a large-width portion which is provided in at least one of lateral parts of a connection portion and gradually widens according to approaching the outer edge wire (23), and the connection portion is a portion of the conductive wire (221) which is connected to the outer edge wire (23). Expressions (1) and (2) are satisfied:A≦100 [μm] (1)B/A≧½ (2).In Expressions (1) and (2), “A” is a width of the outer edge wire (23), and “B” is a largest width of the conductive wires (221) in a portion where the large-width portion (222) is provided.
