Touch sensor and method for manufacturing touch sensor

A touch sensor comprising:

• a first electrode pattern and a second electrode pattern respectively extending in mutually intersecting directions on the same surface of a transparent substrate,
• a first transparent layer having a refractive index of 1.6 or more and a thickness of 200 nm or less and a second transparent layer having a refractive index of less than 1.6 and a thickness of 0.5 μm or more, the first transparent layer and the second transparent layer being sequentially superimposed on the first electrode pattern and the second electrode pattern,
• wherein the first electrode pattern has a plurality of first island-shaped electrode portions disposed at intervals in a first direction on the substrate and first wire portions that electrically connect the first island-shaped electrode portions adjacent to each other, and
• the second electrode pattern has a plurality of second island-shaped electrode portions disposed at intervals in a second direction intersecting the first direction on the substrate and second wire portions that electrically connect the second island-shaped electrode portions adjacent to each other by building a bridge on the first transparent layer and the second transparent layer.
