An object is to provide an illumination device in which uneven light emission that a user may perceive is suppressed. To achieve the object, an illumination device is adopted that includes a power feeding portion and a surface light emitter including a light-emitting surface configured to emit light in accordance with a voltage applied by the power feeding portion and to cause light emission in the shape of a surface. The surface light emitter generates a spatially periodic luminance variation having a substantially constant amplitude.
