Abstract: Provided are an image inspection device and an illumination device capable of thinning and downsizing the illumination device. An image inspection device includes a photographing part photographing an object, a light transmissive illumination part, and an optical member. The illumination part is arranged between the object and the photographing part and has a light emitting surface arranged to face the object. The optical member is arranged on the light emitting surface of the illumination part and transmits light emitted by the illumination part toward the object. The optical member includes a plurality of optical regions. The optical regions are arranged so as to surround a central region of the light emitting surface centered on an optical axis of the photographing part, and are configured to emit light having mutually different color characteristics toward the object.
