Abstract: An information processing apparatus includes: a detection mechanism that includes a transparent substrate on which a detection electrode pattern is provided in biaxial directions and detects, with one of main surface sides of the transparent substrate being an input operation surface, a position on the input operation surface within the biaxial space that an object has touched, the transparent substrate being capable of transmitting near-infrared light; a to-be-authenticated-object placement portion provided in the vicinity of the input operation surface and on which the object is placed as an object to be authenticated; a first light source to irradiate the near-infrared light onto the object to be authenticated; and a photographic camera that is provided on the other one of the main surface sides of the transparent substrate and photographs the object to be authenticated onto which the near-infrared light has been irradiated via the transparent substrate.
