Abstract:
A transfer mold includes a body, a first layer, and a second layer. The body has a projecting-and-recessed surface. The first layer contains an inorganic material and is disposed on the projecting-and-recessed surface of the body. The second layer contains fluorine and is disposed on a surface of the first layer. The average of hardness values of the projecting-and-recessed surface on which the first and second layers are disposed is 30 Hv or higher.

Abstract:
An optical unit having an antireflection function includes a wave surface having a wavelength equal to or shorter than a wavelength of visible light. The wave surface has a curved plane which curves in a recessed shape between an apex portion and a bottom portion of the wave surface. An inflection point of an area of a cross section obtained by cutting through the wave surface in a plane perpendicular to a direction of vibration of the wave surface is positioned toward the bottom portion of the wave surface from a center of the vibration.
