Abstract

An LED is used as an illuminant of an image sensor and includes a fabricated block, a first electrode and a second electrode contained in the fabricated block for transmitting an electric current to a PN surface of a semiconductor that is contained in the fabricated block and secured in a top portion of the first electrode. The semiconductor has a light-projecting axis forming an acute angle with an elongate line of a bottom of the fabricated block.
