Disclosed is an invention relating to an insect trap. The disclosed invention comprises: a main body having formed therein an opening hole for exposing the interior of the main body to the outside an ultraviolet LED lamp comprising an ultraviolet LED for radiating ultraviolet rays, a substrate on the surface of which the ultraviolet LED is mounted, a base for forming an accommodation space for accommodating the substrate, and a pair of electrode pins which are protrudely formed on the base so as to be electrically connected to the substrate and are arranged along the direction of ultraviolet radiation of the ultraviolet LED lamp an installation part comprising an installation board which is installed within the main body, and a socket which is coupled to the installation board and fixes the electrode pins to the installation board such that the ultraviolet LED lamp is installed within the main body and a collection part which is installed in the main body so as to be located adjacent to the ultraviolet LED lamp, wherein the electrode pins are inserted into the socket in an inserted state and are then fixed to the socket after the position thereof is changed to a connected state by rotation in one direction or the other direction of the ultraviolet LED lamp, and the ultraviolet LED lamp with the electrode pins fixed to the socket is installed within the main body such that the direction of ultraviolet radiation of the ultraviolet LED lamp is fixed toward the opening hole.
