Abstract
[Problem] A penlight used for decoration or as a flashlight for the purpose of illuminating the surroundings lacks functionality for optimal enjoyment of a hologram, and no conventional illumination device for a hologram has decorative effect. [Solution] The present invention has a hologram support unit, a light source, and a light diffuser, and by primarily irradiating the light diffuser from the light source, decorative effect is increased, and primarily a hologram image region can be illuminated from a predetermined angle from the same light source or a different light source. Appropriate observation is made possible by making note to an observer on a portion of a medium material integrated with a hologram material whether to irradiate illuminating light from above or irradiate illuminating light from below.
