Abstract
An optical waveguide with photoelectric conversion element includes an under-cladding layer and an over-cladding layer including a thick portion having a large thickness and a thin portion having a small thickness. The optical waveguide with photoelectric conversion element is bendable in a region including the thin portion in such a direction that the under-cladding layer faces inward. This makes it possible to arrange a photoelectric conversion element of each of the optical waveguides with photoelectric conversion element and its associated circuit on the back side of a display panel of an optical touch panel, thereby reducing the size of a frame surrounding a coordinate input region of the optical touch panel and the difference in level on the surface of the frame and its vicinity.
