A flash unit having a light emitting element, and a light condensing plate. The light condensing plate is provided with a surface on which a dimmed light-dispersing print is disposed near the light emitting element for equalizing intensity of the light emitted from the light emitting element. The other side of the light condensing plate contains a convexo-concave surface for condensing the light emitted from the light emitting element. The present invention provides a flash unit, a camera device, and a mobile terminal having a small dimension so as to provide a flash unit having an increased flash light.
