PROBLEM TO BE SOLVED: To provide an insect collector capable of creating an edge as a boundary portion of different lights and having high inset collection efficiency.SOLUTION: In the insect collector, lighting means is arranged in a housing 1 including light transmissive resin plates 3, 4 arranged in a front face opening 2 and an adhesive sheet 5 arranged on the resin plates. In an inner side back face part of the housing 1, a diffuser plate 11 including an intermediate portion raised in a triangular shape is arranged. LEDs 14 for ultraviolet emission are arranged toward one slant face 12 in the triangular shape of the diffuser plate 11 and LEDs 15 for another color emission are arranged toward the other slant face and simultaneous irradiation is executed. Thereby, an edge as a boundary portion of lights can be created along a ridge line of the triangular shape of the diffuser plate 11.SELECTED DRAWING: Figure 2
