The present document relates to an insect trap using an ultraviolet light-emitting diode (UV LED) lamp, and more particularly, to an insect trap using, in place of a conventional UV light source lamp, a UV LED lamp that significantly increases the insect trapping efficiency. One example implementation of the insect trap includes: a UV LED lamp disposed in an air inlet portion of the duct, and including a printed circuit board (PCB) that has a UV LED chip mounted thereon; an installing portion for installing the UV LED lamp on; and a trapping portion provided near the installing portion.
