An image inspection device for inspecting an object (W) by using a photographic image, characterized in that , the image inspection device comprising: a photographing part photographing the object (W); an illumination part comprising a light guide plate disposed at any position between the object (W) and the photographing part ; and a control part controlling the illumination part and the photographing part , wherein the illumination part comprises: a first light emitting part and a second light emitting part disposed around the light guide plate ; and a plurality of reflective parts included in the one light guide plate and comprising a first reflective part reflecting mainly light from the first light emitting part toward the object (W) and a second reflective part reflecting mainly light from the second light emitting part toward the object (W), and the reflective parts are configured so that a light emitting surface of the light guide plate has a first pattern of emission intensity distribution when the first light emitting part emits light under control of the control part , and the light emitting surface has a second pattern of emission intensity distribution different from the first pattern of emission intensity distribution when the second light emitting part emits light under control of the control part . a photographing part photographing the object (W); an illumination part comprising a light guide plate disposed at any position between the object (W) and the photographing part ; and a control part controlling the illumination part and the photographing part , wherein the illumination part comprises: a first light emitting part and a second light emitting part disposed around the light guide plate ; and a plurality of reflective parts included in the one light guide plate and comprising a first reflective part reflecting mainly light from the first light emitting part toward the object (W) and a second reflective part reflecting mainly light from the second light emitting part toward the object (W), and the reflective parts are configured so that a light emitting surface of the light guide plate has a first pattern of emission intensity distribution when the first light emitting part emits light under control of the control part , and the light emitting surface has a second pattern of emission intensity distribution different from the first pattern of emission intensity distribution when the second light emitting part emits light under control of the control part . a control part controlling the illumination part and the photographing part , wherein the illumination part comprises: a first light emitting part and a second light emitting part disposed around the light guide plate ; and a plurality of reflective parts included in the one light guide plate and comprising a first reflective part reflecting mainly light from the first light emitting part toward the object (W) and a second reflective part reflecting mainly light from the second light emitting part toward the object (W), and the reflective parts are configured so that a light emitting surface of the light guide plate has a first pattern of emission intensity distribution when the first light emitting part emits light under control of the control part , and the light emitting surface has a second pattern of emission intensity distribution different from the first pattern of emission intensity distribution when the second light emitting part emits light under control of the control part . <EOS>
