ABSTRACT:
The invention provides a fingerprint input apparatus capable of more stably providing an image “of a higher definition than in prior technologies. The fingerprint input apparatus includes an LED chip10and a solid image pickup device substrate 1 adapted to irradiate a finger20of a fingerprint inputting person with & light from the LED10and bearing a solid image pickup device for receiving light scattered in the interior of the finger, and reads the fingerprint of the finger20based on a light reception signal of the solid image pickup device. The solid image pickup device is constituted of a one-dimensional or two-dimensional image pickup device formed on a rectangular solid image pickup device substrate. A rectangular protective member30is adhered to a side, to be contacted by the finger20, of the solid image pickup device substrate1. In the protective member30, among four sides L1, L2, W1and W2constituting a rectangular external shape, two longer sides L1and L2and a shorter side W1 have the same shape as the external, shape of the solid image pickup device substrate1.
