There is provided an input device capable of judging information not intended for an input operation as unwanted information to input information properly even when the unintended information is sensed during the input of information such as a character with an input element such as a pen. The input device includes an optical waveguide W in a sheet form including an under cladding layer 1 in a sheet form, a plurality of linear cores 2 arranged in a lattice form and formed on a surface of the under cladding layer 1, and an over cladding layer 3 in a sheet form covering the cores 2. A surface part of the over cladding layer 3 corresponding to part of the cores 2 arranged in the lattice form serves as an input region. A CPU for controlling the input device incorporates a program which recognizes pressing as unwanted information when the pressing is sensed at a position at least a distance from the position of a tip input part of the input element corresponding to a number of the vertical or horizontal cores which corresponds to 4% of a total number of vertical or horizontal cores arranged in the lattice form while the tip input part is continuously moved in the input region. |
