摘要： The present invention provides a fiber optical plate comprising (i) a first unit formed by a plurality of first optical fibers which are bundled together and include a core portion and a clad portion and (ii) a second unit optically coupled to the first unit and formed by a plurality of second optical fibers which are bundled together and include a core portion, a clad portion, and an optical absorber made of a material for absorbing the light leaking from the clad portion. The first unit has a first input end surface which is inclined with respect to the center axis of the first optical fibers by an angle at which incident light from within air is prevented from being totally reflected by an interface between the core portion and the clad portion of the first optical fibers and a first output end surface which outputs, of light incident on the first input end surface by way of an object in contact with the input end surface, a light component arriving there after being transmitted through the first optical fibers. The second unit has a second input end surface which is bonded to the first output end surface and a second output end surface which outputs, as an optical image, light arriving there after entering the second input end surface and then being transmitted through the second optical fibers.
