An optical pointing device and a portable electronic device having the same, in which external noise light and/or noise light due to diffused reflection or the like is prevented from being introduced into an optical sensor enhancing precision of operation and providing a housing with improved structure. The device includes an infrared source; a cover having a cover plate transmitting infrared rays from the IR source for reaching a subject out of the cover plate and a cover frame that supports the cover plate; an optical unit in the cover and on which the infrared ray reflected from the subject is incident; and an optical sensor sensing the infrared ray incident thereon from the optical unit; the cover plate has a base coupled to the cover frame, and an IR band-pass filter layer provided on one side of the base.
