An inorganic film base plate is produced with a process comprising the steps of: preparing a surface recess-protrusion base plate, which is provided with a recess-protrusion pattern on a surface, and forming an inorganic film along a surface shape of the surface recess-protrusion base plate, the inorganic film containing a plurality of pillar-shaped structure bodies, each of which extends in a direction nonparallel with the base plate surface of the surface recess-protrusion base plate. Force of physical action may then be exerted upon the thus formed inorganic film in order to separate an on-protrusion film region of the inorganic film and an adjacent on-recess film region of the inorganic film from each other.
