An image inspection device for inspecting an object by using a photographic image, characterized in that, the image inspection device comprising: a photographing part photographing the object; an illumination part comprising a light guide plate disposed at any position between the object 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 (15a, 15c) 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 and a second reflective part reflecting mainly light from the second light emitting part toward the object, and the reflective parts (15a, 15c) 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; an illumination part comprising a light guide plate disposed at any position between the object 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 (15a, 15c) 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 and a second reflective part reflecting mainly light from the second light emitting part toward the object, and the reflective parts (15a, 15c) 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 (15a, 15c) 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 and a second reflective part reflecting mainly light from the second light emitting part toward the object, and the reflective parts (15a, 15c) 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.
