ABSTRACT:
A fingerprint input device capable of obtaining a fingerprint image presenting sufficient contrast is provided. The fingerprint input device includes: a two-dimensional image sensor for picking up a fingerprint image from a fingerprint measured portion of a measurement target finger; and a transparent solid film mounted on an image pickup surface of the two-dimensional image sensor, the fingerprint measured portion being mounted on the transparent solid film when the two-dimensional image sensor picks up the fingerprint image, wherein the fingerprint input device picks up an image of a fingerprint ridgeline portion in the fingerprint measured portion as a light portion, and picks up an image of a fingerprint valley portion in the fingerprint measured portion as a dark portion through an air layer, and a refractive index of the transparent solid film satisfies that contrast of the image is more than a given value.
