Abstract: An input device includes a rectangular sheet-form optical waveguide including a rectangular sheet-form under-cladding layer, a rectangular sheet-form over-cladding layer and linear cores arranged in a lattice pattern and held between the under-cladding layer and the over-cladding layer.

The under-cladding layer and the over-cladding layer each have an elasticity modulus that is set at 10 to 100% of the elasticity modulus of the cores, whereby the cores are prevented from being cracked when the input tip portion of the input element is pressed against the input region or moved on the input region.

Abstract: There is provided a position sensor capable of maintaining the accuracy of the detection of a pressed position with a pen tip, a finger tip and the like even when irregular variations occur in the intensity of light received by a light-receiving element. This position sensor includes: an optical waveguide; a light-emitting element; and a light-receiving element. The position sensor performs a reference setting process for setting the intensity of light which the light-receiving element receives from the cores to a constant reference value not only at the start of use but also intermittently at predetermined time intervals after the start of use. When the light-receiving element senses a change in the amount of light propagating in the cores due to a press during an input operation, the position sensor performs a reference setting stop process for stopping the reference setting process.
